Truth 3-Point Tongue multipoint locks deliver reliable three-point security using horizontal tongue bolts that extend into the door frame at multiple heights. These pre-packaged new construction kits from Truth Hardware include everything needed for installation—gear box, locking bars, strike plates, and upper bar—making them ideal for contractors and homeowners building or upgrading entry door security systems.
Truth Hardware's Sentry series 3-Point Tongue multipoint locks represent a streamlined approach to multi-point door security. Built with 300 series stainless steel components, these systems are engineered for durability and long-term performance in residential and light commercial applications. MPLocks carries these complete kits to help builders and repair professionals find the exact configuration needed for their door height and faceplate requirements. With a standard 45mm backset and 92mm spacing between handle and thumbturn, these locks integrate smoothly with compatible lever trim and euro-style cylinders.
Each Truth 3-Point Tongue kit arrives with all components necessary for a full installation—including the main gear box, upper and lower locking bars, center strike plate, two tongue strikes, and upper bar. This pre-packaged approach eliminates the guesswork of sourcing individual parts and ensures all components are matched for proper function. For contractors working on new construction projects or window and door specialists handling upgrades, having a complete kit reduces installation time and minimizes the risk of compatibility issues.
The 300 series stainless steel construction used in Truth 3-Point Tongue systems provides excellent corrosion resistance and mechanical strength. Unlike painted or plated components that can degrade over time, stainless steel maintains its integrity in varying weather conditions and high-use environments. This makes these locks particularly well-suited for entry doors exposed to moisture, coastal air, or frequent operation in commercial or multi-family settings.
Truth 3-Point Tongue locks are available in both 16mm and 20mm faceplate widths, so measuring your existing door edge or mortise pocket is essential before ordering. The faceplate width must match the routed channel in your door to ensure proper fit and function. Additionally, these kits are sized for specific door height ranges—selecting a kit rated for your door's overall height ensures the locking points align correctly with the frame strikes for secure engagement at all three points.
