This 73 to 81 inch single door multipoint lock kit features Truth Hardware's 5-point hook system, designed for secure replacement on standard residential entry doors. Ideal for homeowners and contractors replacing worn or damaged multipoint locks, these kits include the complete hardware needed for a full installation on single hinged doors within this height range.
When a multipoint lock system fails on a hinged entry door, finding the right replacement kit with matching specifications is essential for restoring security and smooth operation. Truth Hardware's 5-point hook lock kits are engineered for doors measuring between 73 and 81 inches in height, a common range for residential and light commercial applications. MPLocks carries these complete assemblies to help you get your door functioning properly without the guesswork of sourcing individual components. The hook-style locking points provide strong engagement with the door frame, offering reliable security at multiple points along the door edge.
The 5-point hook design distributes locking force across five separate points along the door's edge, significantly improving security compared to single-point deadbolts. Hook bolts pull the door tightly against the weatherstripping when engaged, which also helps with energy efficiency and draft reduction. This configuration is particularly effective for wood and fiberglass doors where a secure, gap-free seal matters for both security and climate control. Truth Hardware manufactures these systems to exacting standards, ensuring consistent performance over years of daily use.
Each kit includes the lock case, extension rods, hook bolts, and necessary mounting hardware for a single door application. This eliminates the challenge of measuring and ordering individual extension pieces separately. Whether you're a professional installer or a capable homeowner, having all components matched and packaged together reduces installation time and the risk of compatibility errors. The faceplate and hardware are designed to work with standard mortise preparations found in most Truth-compatible door systems.
Before ordering, measure your door height from the bottom edge to the top edge of the door slab itself—not the frame or opening. Doors in the 73 to 81 inch range are standard for many residential applications, but confirming this measurement ensures the extension rods and lock case will align properly with your existing strike plate locations. If your door falls outside this range, Truth offers kits sized for other height increments, and getting the correct size prevents costly returns and installation delays.
