Retrofit glass door locks for frameless doors
Clamp-On Glass Door Locks - No Holes Required
If a frameless glass door has already been made and you later decide it needs a lock, drilling the glass is no longer an option. A clamp-on lock fits to the edge of the existing door without requiring holes or cut-outs in the glass.
That makes it particularly useful as a retrofit glass door lock for an already installed frameless glass door. If you are searching for a retro fit glass door lock, this is the no-drill option for an existing door.
Can I add a lock to an existing glass partition door?
Yes. If the frameless door closes against a fixed glass panel with a 6mm gap between them, a clamp-on glass door lock can be added without drilling or cutting the toughened glass. It fits 10mm and 12mm glass. A door that closes into a frame or solid wall needs a different locking arrangement.

Why a Retrofit Glass Door Lock Works After the Glass Has Been Toughened
Toughened glass cannot be cut or drilled after manufacture. Any holes or cut-outs needed for conventional glass door hardware have to be specified before the glass is toughened.
A clamp-on lock avoids that problem because it attaches directly to the edge of the existing frameless door rather than passing through the glass.
01
No Glass Cut-Out
The lock clamps to the edge of the door, so the glass does not need a pre-manufactured hole or lock cut-out.
02
Made for Retrofitting
It can be added after the frameless glass door has already been manufactured and installed.
03
For 10mm or 12mm Glass
The clamp-on lock is suitable for 10mm or 12mm toughened glass doors.
04
Key to Thumbturn
The lock is supplied with 3 keys and uses a key-to-thumbturn configuration, with key operation from one side and thumbturn operation from the other.
Clamp-On Lock or Lever Latch?
The clamp-on lock and lever latch solve different problems.
Clamp-On Lock
Best considered when the frameless door already exists or when you want to avoid holes in the glass. It clamps to the door edge and can be retrofitted later.
Lever Latch
A lever latch is specified as part of the door system before manufacture. On a frameless partition it may require a cut-out in the adjacent glass so the lock can align correctly with the strike plate.
If the door has already been toughened, do not attempt to drill it.
Toughened glass cannot be drilled or cut afterwards.
For Frameless Glass Doors
This clamp-on lock is intended for frameless glass doors. If you are specifying a complete new partition rather than adding a lock to an existing door, it is better to decide the required locking arrangement before the glass is manufactured.
That gives you the choice between the available door hardware rather than limiting the options to components that can be fitted afterwards.
The lock requires an adjacent fixed glass panel to lock against. It is not suitable where the door closes directly into a frame or solid wall. Next-working-day delivery is available when ordered before 12pm.
Planning a New Glass Partition?
If the partition has not yet been ordered, decide whether the door needs to lock before the glass is manufactured. Door hardware that requires glass holes or cut-outs needs to be allowed for at that stage.
For a framed glass door, a lever latch and strike plate can be specified as part of the door system. On a new frameless partition, a glass-prep patch lock is another option when the correct aperture is prepared before toughening.
If you are unsure which lock arrangement is suitable, contact us before ordering the door glass.
Not Sure Which Glass Door Lock You Need?
Send us a photograph or tell us whether the door already exists, whether it is frameless or framed and what it closes against. We can identify whether a retrofit clamp-on lock, a glass-prep patch lock or a lever latch is the right option before you order.
