LCN products are a mix of traditional cast and forged products of the past to modern high technology. Cast iron closer cylinder bodies began as the industry standard in the first half of the 1990s and continue into the new century, to be considered the best material. Forged pistons are also still used in the heavy duty closers being manufactured today.
LCN 4000 Series closers feature a modern design engineered for easy installation and superior performance in an institutional application and other high traffic areas.
LCN concealed closers feature a modern design for concealment in either the head frame or top rail of the door. Closers meet ADA reduced opening force requirements.
Automatic detection and containment of fire and smoke are the best ways to minimize danger to life and property. LCN Sentronic® closer/holders are designed to hold swinging doors open in normal use and release to automatically close the doors under fire conditions.
