An indoor thumbturn lock made from solid metal, finished with Buster + Punch's signature diamond-cut cross knurling on a solid turning knob. Designed for internal bathroom and toilet doors, it includes a safety coin-release on the outer rose so the lock can be opened from outside in an emergency.
Supplied as a pair of thumbturn locks with concealed-fix slim-profile roses, square bar and screw fixings. Pairs beautifully with the matching Cross Knurl door handles and knobs for a fully coordinated door set.

FAQ
Which latch do I need? Pair this thumbturn with a 57 mm deadbolt latch. If you're combining it with door lever handles use a 57 mm backset; door knobs require an 82 mm backset.
Can it be opened from outside? Yes — the outer rose has a coin-release slot so the lock can be opened from the outside in an emergency.
How does the Smoked Bronze finish age? Smoked Bronze is a living finish: with use, the base brass metal gradually shows through for a characterful patina.
