CRL 6″ x 10″ Center Lock Keepers are specially machined to accept the strike from the Push Button Lock. They require no electrical connections so the mounting is exactly the same as our other 6″ x 10″ Center Locks. The lock complies with A.D.A. standards and is ideal for high frequency use in hospitals, entrances to commercial and industrial buildings, apartments, condominiums, schools, etc. The Center Push Button Locks are sold separately. Gaskets are available on special order when using 3/8 inch (10 millimeter) glass doors.
