This cover is ideal for mounting on cam locks that are exposed to dust, dirt, moisture and other elements that can impair the operation of a lock and it prevents any marking of the lock face. Also available with vertical opening, T104. Very easily fitted or retrofitted to most cam locks or switchlocks with a 19mm (.750”) x 16mm (.625”) ‘double D’ profile. The spring-loaded cap snaps shut when the lock is not in use. Made from die-cast alloy with a pressed steel base. An integral neoprene washer provides a seal.
