LCN 4031 with Light Duty Parallel Arm in Aluminum

Product Description

The 4031 is a heavy-duty 4000-series surface closer for high-use commercial and institutional doors. It carries the adjustable spring, separate closing and latch-speed valves, and back-check that define the 4000 line. This is a surface-mounted closer. Configured here as the LCN 4031 with light-duty parallel arm in Aluminum. Adjustable closing and latch speeds let you tune the door to the opening, and the back-check protects the closer and frame from wind or abuse. LCN has been the door-closer of choice for North American commercial buildings for decades.
