Profile Cylinder – Single Sided – Thumb Turn – US3 – Polished Brass - (SC1 / KW1) ( 2-3/4" 66mm )

The profile cylinders always fit and work great. Customers are always happy with the quality

This lock was a good lock for the price. It works as well as other expensive brands. CAUTIoN... just make sure this lock is the size you need. Look at the measurements on the site, measure the lock you are replacing, and check that they match.

Cylinder fits Marks Profile Slimline Mortise. Thumb turn not as nice as Marks version but still usable by my customer. Can't key to Marks A keyway as it is Kwikset keyway, but adjust spacing on last cuts and use Kwikset keyway to key with Marks.
