Glass door patch fittings: 2 per leaf, more with a transom
A frameless glass door takes two patch fittings: F110 at the bottom hinge corner over the floor spring, and F111 at the top hinge corner. A glass transom adds F112 or F114, and F113 sits where transom meets side panel. All five clamp 8 to 12 mm glass.

What each patch fitting does
The five patch fittings look alike from the front. The difference is on the long edge, so read the edge and not the cover plate. Every position below comes from the photographs and position diagrams on the product pages.
| Model | What the edge shows | Where it goes | Glass | Listed finishes |
|---|---|---|---|---|
| F110 | Rectangular socket at the center | Bottom hinge corner of the door, over the floor spring | 8 to 12 mm | SS |
| F111 | One projecting pin | Top hinge corner of the door | 8 to 12 mm | SS, AB, SN, AC, PB |
| F112 | Two bushed holes | Lower edge of the transom, directly above F111 | 8 to 12 mm | SS, AB, SN, AC, PB |
| F113 | Plain, no pin and no socket | Joint between transom and side panel | 8 to 12 mm | None stated |
| F114 | Two bushed holes and an L-shaped end plate | Transom corner at the side of the opening | 8 to 12 mm | SS, AB, SN, AC, PB |
How the parts work together
- The floor spring sits in the floor and controls how the door closes.
- F101 adjusts latch speed and closing speed through built-in screws.
- The floor spring spindle enters the socket in F110, so the door stands on the spring.
- F110 and F111 sit on one vertical line, and the door turns about that line.
- Each patch clamps the glass between two plates, with a green liner between metal and glass.
- On the long patches, screws hold a clamp guard to the glass and a stainless steel cover hides them.
- SS is stainless steel, AB antique brass, SN satin nickel, AC antique copper and PB polished brass.
Three door layouts, three patch counts
Count the glass panels around the door first. Each extra panel adds a patch, so the count sets the order before any finish or price is discussed.
| Layout | Patches to order | Minimum count | Also on the order |
|---|---|---|---|
| Door in a solid opening, no glass above | F110, F111 | 2 | F101, a head fitting for the F111 pin, lock, handle |
| Door under a glass transom | F110, F111, and F112 or F114 | 3 | F101, lock, handle |
| Door with a glass transom and a side panel | F110, F111, F112 or F114, F113 | 4 | F101, lock, handle |
Check these points before you order
- Glass thickness: F110 to F114 are all recorded for 8 to 12 mm (5/16 to 1/2 in) glass.
- Finish: F110 is listed in SS only and F113 has no listed finish, so confirm both if the door is not stainless steel.
- One finish per door: every patch, the lock and the handle should match.
- Glass notches: the F110, F111, F112 and F114 pages each show a recommended notch drawing.
- Tempered glass cannot be cut after tempering, so send those drawings to your glass processor first.
- F113 shows no notch drawing, so its glass preparation is confirmed against your drawing.
- Lock-side corners: the position diagram draws two more patches there and does not name their model, so confirm that corner against your drawing.
- Head fitting: the catalogue has no separate top pivot, so put the fitting for the F111 pin on your inquiry.
Questions buyers ask
What is a patch fitting on a glass door?
A patch fitting is a metal clamp that grips a corner or edge of a frameless glass door. It replaces the hinge and frame fixing that a framed door would use, because tempered glass has no frame to screw into.
Do patch fittings need holes in the glass?
Plan for a notch rather than a hole. The F110, F111, F112 and F114 pages show recommended notch drawings. Every cut must be made before tempering, so fix the models before the glass is ordered.
Can I use these patch fittings on 8 mm or 10 mm glass?
Yes. F110, F111, F112, F113 and F114 are all recorded for 8 to 12 mm glass. Check the handle separately: pull handles 100 to 107 take 10 to 12 mm, and F132 takes 8 to 12 mm.
Which patch fittings do I need if there is no glass above the door?
Order F110 and F111, one each per door. You do not need F112, F113 or F114. You still need a head fitting for the F111 pin, which is not a separate catalogue line, so ask for it on your inquiry.
Are the patch fittings available in black?
Black is not listed. F111, F112 and F114 are recorded in SS, AB, SN, AC and PB. F110 is recorded in SS only. Ask before you specify any other finish.
What load can these patch fittings carry?
No load rating is published for them. Work out the leaf weight, then use the buying test in our guide to standard and heavy duty patch fittings.
