Lcn 4040XPREGAL Heavy Duty Surface Mounted Door Closer Size 1-6

Product Description

The LCN 4040XPREGAL is a heavy-duty, surface-mounted door closer designed for high-traffic commercial and institutional applications. It features an adjustable closing force spanning sizes 1 through 6, allowing field technicians to tune the closer to door weight, frequency of use, and code requirements without replacing the unit. The Super Smoothee hydraulic mechanism delivers consistent, controlled closing action across a wide temperature range. Included TBSRT thru bolts provide a secure, vibration-resistant mounting suitable for metal and solid-core wood doors. At 11.4 pounds, the unit is built for long service life in demanding environments. The 689 aluminum finish blends with standard commercial hardware.

This closer is suited for commercial, institutional, and government facilities where door control reliability is critical. Typical installations include corridors, stairwells, entrance doors, and fire-rated door assemblies in schools, hospitals, government buildings, and correctional facilities. The adjustable size range makes it a practical stock item for service contractors who handle a variety of door sizes and weights across multiple sites. Regular arm configuration is appropriate for standard pull-side or push-side mounting depending on the door swing.
