Trilennium Multipoint Lock Replacement Parts and Components

The Trilennium multipoint lock system represents one of the most recognized American-made multipoint lock designs in the residential door hardware market. Originally developed by W&F Industries, these locks have been installed in countless entry doors across North America. MPLocks maintains a comprehensive inventory of Trilennium replacement components, from lock cases and extension pieces to strike plates and handle trim, helping you restore your door's security without full system replacement.

American-Made Multipoint Lock Construction

Trilennium locks were engineered specifically for the American market, featuring standard 2-3/8 inch backset dimensions that align with typical U.S. door preparations. The system operates with either 3-point or 5-point locking configurations, engaging multiple points along the door edge for enhanced security and improved weathersealing. This design distributes force across the door frame rather than concentrating stress at a single latch point, reducing wear and extending hardware life.

Inswing and Outswing Door Configurations

All Trilennium locks ship configured for inswing door applications. If your door swings outward, you'll need to adjust the panic function before installation by selecting the opposite hand orientation. For a left-hinge outswing door, choose the right-hand inswing configuration. For a right-hinge outswing door, select left-hand inswing. This adjustment ensures proper operation of the multipoint locking mechanism and panic release function.

Identifying the Right Trilennium Replacement Parts

When sourcing Trilennium components, measure your existing faceplate width carefully—options include 1-inch and 7/8-inch profiles. Note the number of locking points (3 or 5) and document the spacing between lock points if replacing extensions. The door thickness and handle hole spacing also affect which trim sets will work with your installation. Having these measurements ready helps ensure you receive compatible parts the first time.
