Privacy For A Bathroom Door, Done Properly
A thumbturn lock in solid metal with the rough cast detail Buster + Punch is known for, designed for internal bathroom and toilet doors. It fits on the room side of a door and turns a deadbolt latch or mortise lock, and it combines with the matching cast door handles and door accessories.
Choose Your Finish
Brass is warm and ages naturally, Smoked Bronze is a deeper darker metal, Steel is bright and neutral, and Welders Black is a matt dark finish.
How It Works
The thumbturn sits on an architectural 4mm thick rose and drives the lock through a 5mm square spindle, with two spindle lengths supplied. It suits locksets and deadbolt latches with 27mm, 38mm or 41.5mm centre distances, and works with tubular deadbolt latches or mortise locks.
Where It Works Best
Internal bathroom and toilet doors between 35mm and 54mm thick with the supplied fixings. A longer spindle and longer bolts are needed for thicker doors. Deadbolt latches are sold separately and Buster + Punch deadbolt latches are listed on this site. For internal use only and not suitable for damp or wet environments.
Made By Buster + Punch
A small detail from a brand that began with door hardware, in the same cast knuckle style as its handles and knobs.
