Also included with this latch is a matching strike plate that fits onto the door frame to house the latchbolt which is 57mm high and 34mm wide including the lip to allow the latchbolt to slide into the frame.

Note: Manufacturing tolerances do apply to all dimensions

Tubular Latches

This tubular latch is ready to fit with any existing or new door handle that comes with an 8mm spindle. Alternatively if you have a smaller spindle size then we have converters available to bring the spindle to 8mm.

If you do additionally need locking capabilities then you can purchase an sashlock that has a latch and lock integrated into a single unit, or you can also purchase a deadlock which is a locking unit only (can be useful if you need to place a lock some distance away from your handle location).
