FAQ
Which latch do I need? This Linear thumbturn is designed to work with a privacy bolt. If combining 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 for emergency opening.
How do the finishes differ? Brass ages gently from radiant to a deeper golden tone; Steel keeps its crisp machined look; Welders Black is a rich off-black PVD coating on solid stainless steel.
