LCN — 4040XP Series

Heavy-Duty Closers

The 4040XP Series is LCN’s most durable surface-mounted heavy-duty closer, designed for the most demanding high-use-and-abuse applications.

It meets ANSI/BHMA A156.4 Grade 1 standards and ADA reduced opening force requirements. This closer is cUL listed and UL listed for self-closing doors without hold-open and boasts a 30-year limited warranty.

The 4040XP Series features include standard non-handed plastic cover, with optional plated finish available for cover, arm and fasteners.

Materials include high-strength cast-iron cylinder, forged steel arm, double heat-treated steel pinion and full complement, low friction bearing for rugged reliability in high-traffic installations.

LCN peel-n-stick templates assure quick and accurate installation, and the patented LCN Green Dial takes the guesswork out of spring force adjustments.
