Lcn 4111HCUSHALRH Door Closer Rh Parallel Arm Hold Open

Product Description

The LCN 4111HCUSHALRH is a heavy-duty door closer designed for right-hand installations using a parallel arm, push-side mount configuration with hold-open functionality. Built for commercial and institutional environments, this unit features an adjustable closing force spanning sizes 1 through 5, allowing field technicians to tune door swing resistance to meet ADA requirements or site-specific conditions. The 689 aluminum finish integrates cleanly with aluminum storefront and hollow metal door assemblies. TBSRT thru bolts are included for a secure, vibration-resistant fastening method. At 12.7 pounds, the closer is robustly constructed for high-cycle applications.

This closer is suited for high-traffic commercial, institutional, and government facilities including schools, hospitals, and secured-access buildings. The parallel arm, push-side mount is the preferred configuration when hinge-side or top jamb mounting is not feasible, or when the door opens toward a wall that would otherwise obstruct a standard arm. The hold-open feature allows the door to remain open at a set position without a separate hold-open device, making it practical for loading areas, service corridors, and accessible entry points where continuous door flow is needed. Licensed door hardware specialists and commercial locksmiths are the primary installers.

Installation Notes

Installation should be performed by a licensed door hardware technician or commercial locksmith familiar with ANSI A156.4 door closer standards. Before mounting, confirm door hand and swing direction to ensure the parallel arm geometry is correct for the opening. Fasten using the included TBSRT thru bolts and verify that backing plates or reinforcement is in place on hollow doors to prevent pull-through. Adjust closing speed, latching speed, and backcheck valves only after the closer is fully mounted and the door is hung square in the frame.
