LCN 4010 & 4040 Closers Pass 10 Million Cycles Test
27/01/2007

LCN is proud to announce that the 4011 and 4041 closers have again successfully passed 10 million cycles during testing performed per ANSI/BHMA A156.4 - 2000 standards. The testing itself took nearly 3 years to complete, during which time no components were replaced, on any closer, at any time. This accomplishment comes after passing previous 10 million cycle testing in 1988 (4010) and 1999 (4040 and 4010).

This provides continuing evidence that LCN still sets the benchmark for quality and durability after product revisions and improvements made since the last round of testing.

The minimum ANSI standard for grade 1 door controls with back check is 1.5 million cycles; which is not a true measure of closer performance in real world environments. In fact, high-traffic doors in large public buildings such as schools, hospitals, and large department stores can expect almost 2 million cycles annually.

Cast iron closer bodies – combined with full complement bearings and double heat treated steel pinions – give LCN the ability to go beyond the minimum requirements and reach 10 million cycle certification.

Relcross can provide electronic copies of the official testing reports from Intertek Testing Services for each of the four closers tested and we would be pleased to share them with end users, architects and customers as a demonstration of LCN’s continued commitment to provide world leading, rugged and reliable door closers.

After all, it’s one thing to claim a closer performs well under extensive life cycles…… it’s another thing to be able to prove it.
