High-traffic doors call for heavy-duty closers
When it comes to heavy-duty, no other closer is like the LCN 4040XP.
Installation and maintenance is made easy, thanks to its intuitive design, on-product diagrams, and a QR code for a landing page full of resources. Installers and service technicians can do their job confidently—ultimately maximizing the life of the product. As a universal closer, the 4040XP fits a wide variety of applications, easing inventory headaches and serving as the closer for all your high use openings.
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.
Every 4040XP includes a high-strength cast-iron cylinder, forged steel arm, double heat-treated steel pinion and full complement, low friction bearings 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. It also includes a non-handed plastic cover and fasteners.
And it all comes with LCN’s roster of expert support staff, based in Princeton, IL. For questions on applications, installations, technical descriptions, or parts, we’ve seen it before and we’re here to help.
