Lcn 4021REGALRH Door Closer Right Hand Top Jamb 689 Aluminum

Product Description

The LCN 4021REGALRH is a right-hand, adjustable door closer designed for top jamb, push-side mounting. It covers closing force sizes 1 through 5, making it adaptable to a wide range of door weights and widths without swapping units. The closer ships with TBSRT thru bolts for secure fastening and is finished in 689 aluminum. Built for demanding environments, it delivers consistent, controlled closing action in facilities where reliable door hardware is not optional. Installation is handled by qualified door hardware or general contractors familiar with ADA and local building code requirements.

This closer is suited for high-traffic commercial and institutional applications including schools, hospitals, government buildings, and correctional facilities. The top jamb, push-side mounting configuration is a common choice where overhead concealment is not required but a clean, accessible installation is needed. The adjustable size range allows a single unit to serve doorways with varying traffic loads, reducing the number of SKUs a facility manager or contractor needs to stock.
