Protect what you’ve built with a Trilennium Multi-Point Locking System.

Security scares? Warping? Gaps around the door? Not anymore. Multi-point lock systems contain several locking points along the length of the door system, which act as separate deadbolts when engaged. Rather than relying on one single lock located in the center of the door panel, multi-point locks have 3-5 locking points that are routed into the door panel and extend into the door jamb or astragal for multi-point reinforcement along the full length of the exterior door system.

The Trilennium®️ Multi-Point Locking System:

  • Runs the along the door for added security and stability. Available in full length coverage and partial coverage options.

  • One turn of the lock engages all the deadbolts, making it as simple as it is strong.

  • Has a solid steel construction that stays secure and strengthens the door edge.

  • Shields against forced entry, extreme wind and pressure, and long-term wear.

Why Trilennium?

All multi-point locks should provide better compression against the weathersealing components of a door, enhance security, and even fix misalignment issues. Here’s how Trilennium does it all -- and does it better than the rest.

  • Trilennium is smarter. Trilennium bolts pre-engage when the door is closed to ensure longevity, smooth operation, and preservation of the door’s alignment, even when the deadbolts aren’t locked.

  • Trilennium works harder.  Trilennium bolts draw the door into even tighter alignment by engaging with the patented Roller Strikes when the lock is activated, meaning homeowners can breathe easy and trust that they’ll have uncompromised, lasting security.

  • Trilennium is stronger. The Trilennium Multi-Point Locking System features a single-piece I-Beam , which strengthens the entire door panel.

  • Trilennium looks better, too. While most multi-point locking systems offer limited styles and finishes, Trilennium has an extensive portfolio of unique, stylish handsets and hardware that are compatible with the Trilennium Multi-Point Locking Systems.
