7/8 Inch Faceplate Trilennium Locks - Multipoint Hardware

Trilennium 7/8 Inch Faceplate Multipoint Lock Replacement Options

The Trilennium 3070 series represents one of the most reliable American-made multipoint locking systems available. Originally designed by W&F Industries, these locks have become standard equipment on many Pella doors and remain a trusted choice for replacement applications. At MPLocks, we stock these 7/8 inch faceplate assemblies in both left-hand and right-hand inswing configurations, each featuring a 60mm (2-3/8 inch) backset that matches common residential door preparations.

Durable Construction for Long-Term Security

Each Trilennium 3070 lock assembly features a stainless steel faceplate measuring approximately 65-9/16 inches in length with radius ends. The three-point engagement system combines a deadbolt with two locking latch bolts, creating multiple points of contact between the door and frame. This design distributes force across the door edge rather than concentrating stress at a single lock point, helping resist forced entry attempts and reducing wear over time.

Versatile Handing for Inswing and Outswing Doors

While these locks arrive configured for inswing doors, they can be adapted for outswing applications by reversing the panic function before installation. For left-hinge outswing doors, select the right-hand inswing lock; for right-hinge outswing doors, choose the left-hand inswing version. This flexibility makes the Trilennium 3070 suitable for a wide range of door configurations without requiring separate outswing-specific hardware.

Confirming the Right Lock for Your Door

Before ordering, verify your existing faceplate width measures 7/8 inch (22mm) rather than the wider 1 inch version also available in the Trilennium line. Check the backset measurement from the door edge to the center of the handle bore—these locks require a 2-3/8 inch (60mm) backset. Door handing is determined from the exterior: if the hinges appear on the right side, you have a right-hand door. Taking accurate measurements ensures the replacement lock fits your existing door preparation without modification.
