The 4040XP is LCN’s most durable and flexible heavy duty surface mounted closer, designed for institutional and other demanding high traffic applications. The 4040XP sets a new standard for reliability, longevity and value with a beefier design and extraordinary performance testing that goes far beyond industry requirements. We built the 4040XP from the inside out, combining tougher, bolder construction with proven LCN technology. The result is a closer that’s stronger, smarter and delivers remarkable value in a variety of applications.
The patented green dial on the 4040XP makes spring adjustments fast, easy and foolproof. The all-weather fluid reduces maintenance and ensures consistent performance through every season. High-traffic doors call for heavy-duty closers – closers that won't let you down no matter how many people go through the door or how hard they kick, push or slam against it.
