    Trine Access Technology: The World's Smallest and Strongest Electric Strikes

    In the access control world, Trine is known for solving the problems that other manufacturers can't. Famous for producing the "Smallest Electric Strikes in the World," Trine's 3000 Series allows for installation in tight frames where a standard strike simply won't fit. At Lock Depot, we recommend Trine for technicians who need universal compatibility and outdoor-rated reliability.

    We stock the Trine 4100 series, the ultimate "one-box" solution that includes multiple faceplates to work with nearly any cylindrical or mortise lock. For outdoor applications, the Trine EN series is the gold standard -- it's the only UL-listed outdoor-rated strike that can handle the elements on gates and perimeter fences. When you run into a "mystery frame" or a difficult gate prep, Trine is usually the answer.

    PRO TIP: The "Shallow Backset" Advantage

    Installing a strike into a 2" fire-rated aluminum frame? The Trine 4100 features a shallow 1-3/8" backset, meaning you don't have to worry about hitting the sheetrock or structural steel behind the frame. It's a massive time-saver for retrofit projects in modern office buildings.

    Trine electric strikes ship from our warehouses across America. Stocking dealer with outdoor gate and perimeter fence expertise.

    Trine Electric Strikes FAQ

    What makes Trine strikes different from HES or RCI?

    Trine specializes in compact and universal-fit strikes. Their 3000 Series is the smallest electric strike available, fitting frames as narrow as 1-1/4". The 4100 ships with multiple faceplates in one box, making it a true "universal" solution for retrofit jobs where the lock brand or frame type is unknown.

    Can I use a Trine strike outdoors on a gate?

    Yes. The Trine EN Series is specifically designed for outdoor use and is UL-listed for wet locations. It features a sealed housing that protects the solenoid from rain, dust, and temperature extremes, making it ideal for gates and perimeter fences.

    Does the Trine 4100 work with mortise locks?

    Yes. The 4100 includes interchangeable faceplates for both cylindrical and mortise locksets. This "one-box" approach eliminates the guesswork on retrofit projects and reduces the number of SKUs a technician needs to carry on their truck.
