This LCN closer solves high-traffic wear problems in commercial openings while maintaining ANSI Grade 1 performance standards. The parallel arm configuration keeps the closer arm out of the traffic path, reducing damage from carts and foot traffic.
Built with forged steel main arm and double heat treated steel pinion for durability. Cast iron body construction handles heavy use cycles. All weather fluid maintains consistent closing performance across temperature ranges. Left hand configuration includes TBSRT thru bolts for secure mounting through hollow metal frames.
