Cylindrical Lever Lock and Fire-rated Tubular Lock

Over the course of more than 30 years, the evolution of market demands has rendered older latch designs obsolete, failing to meet the contemporary standards of functionality and reliability. The E590SUS has emerged as an innovative tubular lock latch responding to these changing needs.

With a lightweight spring, extended lifespan, high test strength, and exceptional fire resistance, this latch is suitable for cylindrical lever lock and fire-rated tubular lock. In particular, the latch's lifespan of up to 1 million cycles ensures long-term durability and reliability, minimizing the need for replacements or repairs.

Furthermore, the E590SUS has undergone rigorous testing by BHMA A156.36 standards, achieving exceptional test parameters that rival those of Grade One latches. These outstanding results reflect the latch's superior quality and dependability, making it a trustworthy choice for securing doors in various settings.

Due to its impressive fire resistance and robust construction, the E590SUS is particularly suited for use in fire doors, public venues, hospitals, offices, and residential homes. Its ability to withstand high temperatures and provide reliable security makes it an ideal solution for environments where safety and security are paramount.

Additionally, the latch incorporates a robust die-casting spindle follower, engineered to endure daily wear and tear while maintaining consistent performance. Lastly, the E590SUS boasts a protective 1.0mm thick iron case, adding an extra layer of strength and reinforcement to the design.
