The 4040XP Series is LCN’s most popular door closer—and for good reason. This durable non-handed, surface-mounted heavy-duty closer, is designed for the most demanding high-use-and-abuse applications as well as for easy installation and maintenance. With new enhancements made to the 4040XP, installers and service technicians can have confidence in how to install and adjust the door closer properly—ultimately, maximizing the life of the product.
It’s ANSI/BHMA A156.4 Grade 1 rated and meets ADA reduced opening force requirements. It’s 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 LCN Green Dial takes the guesswork out of spring power adjustments.
