LCN 4040XPEDAAL Parallel Arm Super Smoothee Heavy Duty Adjustable 1-6 Surface Mounted Regular Door Closer with TBSRT Thru Bolts and Extra Duty Arm

The 4040XPEDAAL is a parallel arm surface mount door closer designed for heavy-duty commercial applications. It mounts on the push side of the door frame with a parallel arm configuration, making it ideal for high-traffic entrances where traditional closers would interfere with door operation. This LCN closer solves the problem of maintaining consistent closing force and speed in rugged environments while meeting accessibility requirements.

Built with cast iron construction and forged steel arms, this closer handles the punishment of continuous use. The Green Dial adjustment system removes guesswork from spring power settings, while the spring-loaded stop in the soffit shoe provides reliable positioning. The adjustable power range accommodates doors up to 5 feet for interior applications and 4 feet for exterior doors.

This closer meets ANSI/BHMA A156.4 Grade 1 standards for commercial door control hardware. Grade 1 door closers provide the highest performance rating for heavy-duty applications.
