Shop replacement Lockmaster 104 and 304 multipoint door locks. Lockmaster gearbox's feature an 8mm double spindle with 62/92mm centers. Available in 35mm and 45mm backsets. Double spindle gearboxes are unsprung and therefore not suitable for use with unsprung handles. Handles must have a spring cassette.

Only gearbox available is with the latch and deadbolt. Lockmaster also had a version that uses a hook in place of the deadbolt. That version has been discontinued. Please contact us for replacement.
