Truth 73"-81" Single Door 3-Point Multipoint Lock Kit

Truth 3-Point Tongue Multipoint Lock Kits for 73-81 Inch Single Doors

When a multipoint lock system fails on a standard-height entry door, finding the right replacement kit can be the difference between a quick repair and a costly door replacement. MPLocks carries Truth 3-point tongue lock kits specifically sized for single doors in the 73 to 81 inch range—one of the most common door heights in residential construction. These kits work with tongue-style locking points that engage into strike plates along the door frame, creating multiple points of contact for improved security and weathertight sealing.

Complete Kit for Streamlined Installation

Each 3-point tongue kit includes the gearbox, tongue extensions, and necessary hardware to complete your repair. The tongue mechanism operates smoothly with a single handle motion, extending locking points at the top, middle, and bottom of the door simultaneously. This design eliminates the need for separate deadbolts while distributing locking force across the full height of the door, reducing frame stress and improving overall door alignment over time.

Compatible with Truth Hardware Systems

These kits are engineered as direct replacements for existing Truth multipoint lock systems. If your current door uses Truth hardware—commonly found in quality wood and fiberglass entry doors from various manufacturers—this kit provides factory-spec components that match your existing strike plate locations and handle preparations. No frame modifications are typically required when replacing like-for-like hardware.

Measuring Your Door for the Right Kit

Before ordering, measure your door height from the bottom edge to the top edge—not the visible opening. Doors in the 73 to 81 inch range fit this kit, but if your measurement falls outside this window, browse adjacent size kits to ensure proper extension placement. Also confirm your current system uses tongue-style locking points rather than hooks or shootbolts, as the mechanism type must match for proper frame engagement.
