This corner strike box is the keep that a glass door patch lock bolts into, fitted at the corner where the door meets the transom (overpanel) and side panel. It clamps over 10–12mm toughened glass and gives the lock bolt a solid, neat housing. It suits shopfronts, offices, reception areas and internal glass partitions.
It has a satin stainless finish to match standard patch fittings. A replacement corner strike box is a quick fix if your old keep is damaged, worn or stops the door locking properly.
Why choose this corner strike box?
- Easy fit: clamps straight over the glass with gaskets. No drilling into the frame is needed on standard pre-cut glass.
- Strong and secure: a solid diecast body gives the patch lock bolt a firm keep.
- Fits 10–12mm glass: works with the standard toughened glass used on frameless doors and overpanels.
- Matching finish: the satin stainless look blends in with satin patch locks and corner fittings.
- Great value replacement: replace just the strike instead of the whole fitting set.
- Fast UK dispatch: in stock and shipped quickly, so your door is secure again fast.
