Glass door patch lock: F123 for 12 mm, GL125 SS up to 10 mm
For a glass door patch lock on 8 to 12 mm glass, order F123: a clamp-on body with a cylinder and a bolt that drops into a floor socket. For a pair on 8 to 10 mm glass, order GL125 SS. G130 and 410 have no published glass thickness.

Four patch locks compared
A patch lock clamps onto the glass like a patch fitting, so a frameless door needs no lock stile. The first choice is what the bolt locks into: the floor, a strike plate, or a second lock body on the other leaf.

Which lock for which door
| Door | Order | Why |
|---|---|---|
| Single door, 8 to 12 mm glass | F123 | Published range covers the door, and the photographs show the floor socket with it |
| Single door, bolt into a strike plate | G130 | The photographs show a strike plate and two screws. Glass thickness confirmed against your drawing |
| Pair, 8 to 10 mm glass | GL125 SS | One lock across the meeting edges, recorded for double doors and for left and right use |
| Pair, 12 mm glass | F123 on each leaf, or 410 | GL125 SS stops at 10 mm. Use 410 only once its glass thickness is confirmed against your drawing |
What the glass and floor need
- F123: the exploded drawing on its page shows the body seated in a notch at the glass edge.
- Notches must be cut before tempering, so choose F123 before the glass is ordered.
- F123: the floor socket needs a recess in the floor where the bolt lands.
- GL125 SS: we list no cutting or drilling of the glass.
- GL125 SS: clamp plates grip the glass, and two screws secure them.
- G130 and 410: glass preparation is not published, so it is confirmed against your drawing.
What to confirm on your quotation
- Cylinder function: key on one side or both sides.
- Key count per lock.
- Keyed alike or keyed differently across a project.
- Floor socket included with F123, as the photographs show.
- Finish, because F123 has no listed finish and GL125 SS is SS.
- Local exit rules, if the door is on an escape route, because a keyed bolt may not be allowed there.
Questions buyers ask
What is a glass door patch lock?
It is a lock body that clamps onto the glass edge, in the same way a patch fitting does. It gives a frameless door a key lock without a stile. F123 and G130 lock a single leaf. GL125 SS and 410 lock two leaves together.
Can I fit GL125 SS to 12 mm glass?
No. GL125 SS is recorded for 8 to 10 mm glass. For 12 mm glass order F123, which is recorded for 8 to 12 mm.
Do I need to drill the glass for a patch lock?
It depends on the model. GL125 SS installs without cutting or drilling. F123 is drawn in a glass notch, which must be cut before tempering. For G130 and 410, confirm against your drawing.
Which patch lock suits a pair of glass doors?
On 8 to 10 mm glass, order one GL125 SS across the meeting edges. On 12 mm glass, order F123 on each leaf, with a floor socket for each. 410 is also a two-body lock, but its glass thickness must be confirmed first.
Can several doors share one key?
Keying options are not published for these locks. Give the door count and the keying you want on your inquiry, and have it confirmed on the quotation.
