Truth 71"-79" Single Door 3-Point Multipoint Lock Kit

Truth 3-Point Tongue Multipoint Lock Kits for 71-79 Inch Single Doors

When a multipoint lock fails on a standard single entry door, finding the right replacement kit with matching specifications is essential for restoring security and proper function. Truth Hardware's 3-point tongue multipoint lock systems are engineered for doors measuring between 71 and 79 inches in height—a common range for residential and light commercial applications. MPLocks carries these complete kits to help customers avoid the hassle of sourcing individual components, ensuring all parts work together seamlessly for a successful installation or repair.

Complete Kit Components for Reliable Installation

Each 3-point tongue kit includes the gearbox, extensions, and tongue bolts required for a fully functional multipoint locking system. The tongue-style locking points engage into strike plates mounted on the door frame, providing secure engagement at multiple heights along the door edge. This configuration distributes locking force across three points rather than relying on a single deadbolt, which helps prevent warping and improves overall door seal and weatherproofing performance.

Designed for Single Door Applications

Unlike double door kits that require coordination between active and passive panels, these single door kits are streamlined for straightforward hinged door installations. Whether you're replacing a worn-out Truth multipoint system or upgrading from a standard single-point lock, these kits provide a direct solution. The 3-point configuration offers an excellent balance between security and simplicity, making it a popular choice for residential entry doors.

Measuring Your Door for the Right Kit

Accurate door height measurement is critical when selecting a multipoint lock kit. Measure from the top of the door slab to the bottom—not the frame—to determine which height range applies. For doors falling between 71 and 79 inches, this kit provides the correct extension lengths and gearbox positioning. If your door measures outside this range, Truth offers kits for other height intervals to ensure proper lock point alignment and smooth operation.
