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.
Submit photos and measurements and we will help match the correct lock, gearbox, handle set, or replacement part.
