Patch fittings
Patch fittings are metal clamps that grip toughened glass at the corners of a frameless door or panel. They connect the glass to the floor spring, top pivot, lock or adjoining panes, using gaskets between metal and glass so that no frame is needed.
Where does it work well?
Frameless toughened glass doors and screens on shop entrances, offices and showrooms, where the aim is an uninterrupted glass view with visible metal limited to small corner fittings.
Pros
- Keeps the frontage visually clear
- No frame around the glass
- Available in steel, brass and coated finishes
Cons
- Only suit toughened glass of the right thickness
- Can slip if under-tightened or the gasket wears
- Glass must be notched or sized for them
How long does it last?
Typically many years, though gaskets and grub screws may need attention on a busy door.
What should you check when buying?
Confirm the fitting suits the glass thickness, usually 10 or 12 mm, and the door weight. Check that the pivot centres match the floor spring. Match top and bottom patches to the lock type, and ask for spare gaskets when you order.
Common questions
Why has my glass door dropped in its patch?
Usually the gasket has worn or the clamping screws have loosened, so the glass slides under its own weight. Stop using the door and have it reset, because glass touching metal can chip and then break suddenly.
Can patch fittings be reused with new glass?
Often yes, if the metal is undamaged and the size is right. Gaskets should be renewed, and the new toughened panel must be made with the same notches and centres as the old one.
