Lcn 4111HCUSHALLH Door Closer Left Hand Parallel Arm Hold Open

Product Description

The LCN 4111HCUSHALLH is a heavy-duty, parallel arm door closer designed for push-side mounting on left-hand doors. It features a cushioned parallel arm assembly with a hold-open function, allowing the door to remain open at a set position until manually released. Closing speed is adjustable across a range of 1 through 5, giving installers control over latch speed and sweep speed to meet code requirements or facility preferences. The closer ships in a 689 aluminum finish suited for commercial door frames and architectural hardware schedules. At 12.6 pounds, it is built for high-cycle, high-traffic applications.

This closer is appropriate for commercial and institutional installations including schools, hospitals, government buildings, and similar high-traffic facilities where controlled door movement and hold-open capability are required. The push-side, parallel arm configuration is common in corridor and vestibule openings where swing clearance on the pull side is limited. The hold-open cushion mechanism allows the door to stay open without a separate floor or wall stop. Thru-bolt mounting hardware (TBSRT) is included for secure frame attachment.

Installation Notes

Installation is performed by a licensed door hardware technician or commercial locksmith familiar with ANSI/BHMA closer standards and ADA door-force requirements. Before mounting, confirm door hand, frame condition, and swing clearance are appropriate for a parallel arm push-side application. Power tools are used for thru-bolt installation; verify backing material in the door frame can accept the TBSRT bolt pattern. Adjust sweep speed, latch speed, and hold-open position after mounting with the door in the open position per the manufacturer adjustment sequence.
