Glass door installations pose a particular challenge when selecting hardware. The narrow aluminium frames, the need for clean aesthetics, and the constant foot traffic in commercial environments all demand a more considered solution than a standard lock.
You may manage a retail unit with full-height glazing across the frontage. Or you can oversee access to an office block where staff come and go at all hours. Either way, the mechanism needs to withstand repeated use while fitting within profiles only 30mm wide. What follows is a practical look at some of the most reliable commercial door locks available, specifically from the Lockey range, which has been a staple in keyless entry since 1982.
Top 5 Commercial Locks for Glass Door Applications
Before considering broader issues, it helps to understand which specific products are best suited for glass installations. These five have proven themselves across retail premises, offices, and public buildings throughout the United Kingdom.
1. Lockey 7055 Super 8 Mortise Latch
The 7055 sits at the heart of the Super 8 series, designed specifically for narrow-stile aluminium doors. What makes it worth considering? The body measures just 30mm wide, so it slots into most frames without modification.
This mortise latch mechanism automatically deadlocks when closed, so you do not need to secure items manually. Staff simply pull the entrance shut behind them. For buildings with steady daytime visitor flow, a passage mode allows free movement without requiring code entry each time. Then, after hours, a quick code change returns everything to secure mode. Installation requires standard narrow-stile preparation, and the unit works equally well in left- or right-hand hung configurations.
2. Lockey Super 8 7075 Retrofit Lock
Sometimes the existing hardware has failed, but the prep remains intact. That is where the 7075 becomes useful. This retrofit model fits into the cutout left by Adams Rite narrow stile latches, one of the most common commercial fittings in the UK market.
The advantage here is speed. Rather than re-machining the entire frame, remove the old unit and install the 7075. The push-button keypad offers combination entry with up to six digits, and the mechanism itself is entirely mechanical. No batteries to replace, no wiring to run. For property managers dealing with multiple sites, that simplicity translates into lower ongoing maintenance costs.
3. Lockey Super 8 7070 Push Button Lock
The 7070 represents the most versatile option in the narrow stile lineup. Built with the same 30mm body width, it accommodates a range of backset dimensions and is suitable for both new installations and retrofit applications.
One thing worth mentioning: the combination can be changed without removing anything from the frame. That feature alone saves considerable time when tenant turnover happens or when you need to revoke access quickly. The stainless steel buttons resist corrosion even in exposed locations, and the overall construction meets the demands of high-cycle use. If your premises receive hundreds of entries per day, this unit will not struggle.
4. Lockey 2500 Hook Bolt for Sliding Doors
Sliding glass panels require entirely different hardware. Standard deadlatches and spring bolts will not work because the panel moves parallel to the frame rather than swinging away from it. The 2500 addresses this with a hook bolt mechanism that curls around the strike when engaged.
What does that mean in practice? Even if someone attempts to pry the hook open, it remains seated. It is a far more secure arrangement than the simple catches that come standard with many sliding systems. The 2500 suits both internal partitions and external points; for exterior applications, consider additional weatherproofing measures based on exposure.
5. Lockey 2210 Mortise Deadbolt Digital Lock
When you need maximum holding power without any spring-loaded components, a mortise deadbolt provides it. The 2210 inserts a solid bolt into the frame, and that bolt remains in place until the correct combination is entered.
This model works particularly well at entrances to secure areas, such as server rooms, stock rooms, or private offices within larger premises. The push-button interface keeps things straightforward for users, while the mechanical internals eliminate electronic failure points. It mounts into a standard mortise preparation, and like other Lockey products, the combination can be changed as needed without specialist tools.
6. Lockey LD930 Narrow Style Latch
Purpose-built for commercial glazing systems where frame width limitations prevent standard mortise fitment, the Lockey LD930 narrow style delivers Adams-Rite-compatible performance within restricted cavity dimensions. This model suits shopfront installations, office partitions, and glass-fronted retail units where the architectural elegance of slim aluminium profiles would reject conventional hardware without specialist engineering.
The slim profile integrates seamlessly with commercial glazing systems common across UK high streets, maintaining clear sightlines through transparent panels whilst providing robust mechanical combination access. Property managers appreciate the elimination of key distribution logistics in multi-tenant buildings where staff turnover creates ongoing administrative complications across multiple glass access points, and the mechanical construction ensures reliable function regardless of weather exposure or electrical availability.
Understanding Different Types of Locks for Commercial Glass Installations
Beyond specific product recommendations, it is helpful to understand the broader hardware categories suitable for these applications. Each type has its place depending on requirements, configuration, and usage patterns.
Mortise Locks
These require a pocket cut into the stile to house the body. Mortise locks offer excellent security because the mechanism sits protected within the frame rather than mounted on the surface. For aluminium-framed installations, narrow-stile versions have become the standard.
Deadbolts and Hook Bolts
A deadbolt throws a solid bolt into the receiving strike, providing strong resistance to forced entry. Hook bolts work similarly but curve around the strike, making them ideal for sliding applications where lateral force could otherwise defeat a straight bolt.
Surface-Mounted Options
Where prep is limited or the profile does not accommodate internal mounting, surface rim units offer an alternative. The Lockey 2200 Surface Rim Lock falls into this category, mounting directly onto the face and engaging with a strike on the frame.
Cylinder Locks and Profile Cylinder Systems
Traditional cylinder lock hardware uses a keyed cylinder to operate the bolt or latch. While less convenient than keyless options, cylinder locks remain popular where physical key control is preferred. Profile cylinder fittings allow the cylinder to be swapped without replacing the entire mechanism.
Why Commercial Door Locks Differ from Residential Hardware
A question that comes up fairly often: can standard residential units be used for commercial glass installations? Technically, sometimes. Practically, rarely well.
The differences stem from construction standards and usage requirements. Commercial hardware typically meets higher durability ratings, often tested to hundreds of thousands of cycles. Residential versions might fail after a fraction of that use. The Builders Hardware Manufacturers Association grades these from 1 to 3, with Grade 1 being the most robust. Commercial applications almost always call for Grade 1 or Grade 2 hardware.
Frame dimensions also matter. Residential door locks require a stile width that aluminium frames often do not provide. Trying to fit a standard deadbolt into a narrow profile either requires significant modification or simply will not work. Purpose-built narrow stile units exist precisely because this mismatch is so common.
Then there is the matter of access control. A residential front entrance may see two or three dozen entries per day. A commercial one could see hundreds. The hardware must withstand that punishment while remaining easy to operate, and the system must support multiple users, potentially with different permission levels or time-based restrictions.
Securing Full-Height Glass Door Installations
Full-height panels, whether framed or frameless, present their own challenges. The transparency that makes them architecturally appealing also means any clunky fittings stand out visually. And with frameless designs, you lose the convenient stile into which a mortise unit would normally fit.
For Framed Installations
Narrow stile hardware remains the go-to solution. The Lockey Super 8 series and dedicated narrow style locks fit frames as narrow as 30mm, maintaining a clean profile while providing genuine protection. Choose between mortise latches for convenience or mortise deadbolts for maximum holding strength.
For Frameless Designs
Options become more limited here. Patch fittings that clamp onto the panel can incorporate mechanisms, though these typically require professional installation to ensure proper alignment and adequate clamping pressure. Some electronic solutions use magnetic units mounted at the top or bottom that engage with a strike on the frame or floor. A smart lock system may suit high-end installations where app-based control and audit trails are critical.
Worth noting: UK Building Regulations require safety glass in these applications, either toughened or laminated, to BS EN 12600. This applies regardless of the hardware type fitted. Any panel within 1500mm of floor level must break safely if broken at all, fragmenting into small granular pieces rather than dangerous shards.
Is Commercial Glass Always Tempered?
Building regulations effectively mandate it, yes. Any glazing in a “critical location,” including entrances and side panels, must be safety-rated. A toughened material meets this requirement due to its fracture behavior. The tempering process creates internal stresses that cause fragmentation into small, relatively harmless pieces upon breakage.
For commercial applications, toughened panels typically measure 10-12mm thick, providing both safety compliance and reasonable impact resistance. Laminated alternatives offer another route, sandwiching a plastic interlayer between sheets to hold fragments together even when the material is broken.
The hardware must be compatible with the thickness and frame type. When ordering, always specify the exact configuration to ensure compatibility.
Best Hardware Choices for Unframed Installations
Frameless designs require fittings that clamp directly to the panel rather than being mounted in a stile. Several approaches work:
Patch Fittings with Integrated Mechanisms
These metal plates clamp onto the panel near the bottom or top corner, with the mechanism built in. They require precise preparation and professional fitting, but result in a very clean appearance.
Floor Springs with Locking Function
For pivot-hung, frameless entrances, floor springs can include a locking position that holds the door closed. Entry typically requires a separate unit at handle height.
Bolt-Through Hardware
Some products designed for frameless applications clamp from both sides using bolts that pass through the panel. This requires drilling holes into the toughened material before tempering, so planning is essential. Hinge placement must also be considered during this preparation stage.
For most commercial applications where frameless designs are desired, working with a specialist contractor ensures the hardware and panel specification coordinate properly.
Additional Products Worth Considering
The five highlighted earlier suit the most common scenarios, but Lockey offers additional options that address specific situations.
The Lockey 2430 Mortise Latch features a spring latch and push-button entry, ideal for internal installations where deadbolt protection is unnecessary but keyless convenience remains valuable.
For cabinet and display case needs, the Lockey LC150 Hook Bolt protects sliding panels on retail fixtures. The LC200 Push Button Cabinet Lock offers similar protection for hinged cabinet configurations.
The Lockey 1150DS provides combination entry from both sides, useful where staff enter from the front and deliveries arrive at the rear through the same point.
Where panic hardware or night latches already exist, the Lockey 2230NL Front mounts onto the existing case, adding keyless function without replacing the entire mechanism.
The Lockey 2435 Mortise Latch With Hold Back is suitable for locations that need a hold-open feature during busy periods, while the Little Lockey L235 and L220 models work well for lighter-duty internal applications. For those needing key override capability alongside push-button entry, options are available across the range with various part configurations.

Frequently Asked Questions
What distinguishes commercial units from standard residential hardware?
Commercial hardware meets higher durability standards, typically Grade 1 or Grade 2 under BHMA classifications, meaning it withstands many more cycles before wearout. Residential versions often reach Grade 3 at best. Beyond durability, commercial products accommodate narrower stiles common in aluminium-framed installations, whereas residential ones assume timber dimensions. The control features also differ; commercial settings often require changeable combinations, multiple user codes, or passage modes to meet varying requirements throughout the day.
Can mechanical push-button units provide adequate protection for exterior commercial entrances?
Yes, provided you choose quality hardware designed for the purpose. Mechanical push-button products from reputable manufacturers such as Lockey undergo extensive testing and use hardened components that resist tampering. The absence of electronics actually eliminates certain vulnerabilities; there are no batteries to fail, no circuits to short, and no wireless signals to intercept. For many applications, a well-installed mechanical unit provides protection that is equal to or exceeds electronic alternatives while requiring far less maintenance over its lifespan.
How frequently should combination codes be changed?
This depends on your circumstances, though quarterly changes suit many businesses. High-turnover environments, such as retail with seasonal staff, might change codes monthly or whenever employees leave. Offices with stable teams could manage with semi-annual changes. The critical factor is to change codes whenever someone with entry privileges departs, regardless of the scheduled rotation. Lockey products allow code changes without removing the unit, making this maintenance task straightforward and quick.
What maintenance is required for mechanical keyless products?
Remarkably little compared to electronic systems. An annual inspection to check bolt throw and engagement, occasional cleaning of the keypad face, and light lubrication of moving parts if the mechanism feels stiff. Avoid petroleum-based lubricants; a dry graphite lubricant or silicone spray works better. The mechanical nature means no battery replacements, no software updates, and no network connectivity issues. Most quality units run for decades with only this minimal attention.
Are narrow stile products suitable for fire-rated assemblies?
This requires careful specification. Fire-rated assemblies must use hardware listed for that purpose, and the entire unit, including the frame, panel, and hardware, must be certified as a complete system. Some Lockey products carry appropriate fire ratings when installed in accordance with the manufacturer’s specifications. Always verify compatibility with your specific fire requirements and consult the manufacturer’s approved hardware list before proceeding.
