Fuhr Roundbolt Multipoint Locks - Replacement Parts

Replacement Solutions for Discontinued Fuhr Roundbolt Multipoint Locks

Fuhr roundbolt multipoint locks were engineered for European-style entry doors, utilizing round locking bolts positioned above and below the handle cylinder to engage the frame at multiple points. These locks were commonly installed on doors ranging from 77 to 80 inches in height, featuring either 45mm or 55mm backsets and standard 92mm or 70mm PZ spacing. Although Fuhr has discontinued production of these specific roundbolt models, MPLocks maintains replacement kits that allow homeowners and contractors to restore proper lock operation without replacing the entire door system.

Understanding Fuhr Roundbolt Lock Construction

Roundbolt locking mechanisms differ from tongue or shootbolt designs by using cylindrical bolts that rotate into strike pockets in the frame. This design provides solid engagement and was favored for its durability in residential applications. Fuhr roundbolt locks typically include a center deadbolt along with the roundbolt latches, creating a three-point or multi-point security system. The automatic release feature on some models allows the roundbolts to retract when the handle is operated, simplifying daily use while maintaining security when locked.

Replacement Kit Compatibility for Existing Installations

When replacing a discontinued Fuhr roundbolt lock, the key measurements to verify include backset (45mm or 55mm), PZ spacing (the distance between handle center and cylinder center), handle height, and overall faceplate length. Some replacement kits convert roundbolt locks to tongue-style operation while maintaining the same cutout dimensions and strike locations. This approach allows for restoration without modifications to your door or frame, preserving the original hardware footprint while using currently available components.

Measuring Your Fuhr Roundbolt Lock for Replacement

Before ordering a replacement kit, measure the backset from the edge of the door to the center of the cylinder hole. Then measure the PZ spacing from the center of the handle spindle to the center of the cylinder. Note the handle height—measured from the bottom of the faceplate to the center of the handle—and the overall length of the lock assembly. Faceplate width (typically 16mm or 20mm) must also match your door's existing mortise pocket. These measurements ensure your replacement kit will install correctly without door modifications.
