Lcn 4041DEL-EDA 689 Surface Door Closer Adjustable 1-6

Product Description

The LCN 4041DEL-EDA 689 is a Grade 1 surface-mounted door closer with a delayed-action feature and an extra duty arm, designed for commercial and institutional door applications. It mounts on the push side of the door and allows a full 180-degree swing. Closing force is field-adjustable across sizes 1 through 6, making it suitable for a wide range of door widths and weights. The unit ships with a plastic cover and features an aluminum painted finish. Installation is non-handed, so a single part covers both left- and right-hand door swings.

This closer is intended for commercial interior and exterior doors in settings such as offices, schools, hospitals, and government facilities. The delayed-action function holds the door open briefly before initiating the closing cycle, supporting ADA-compliant traffic flow and high-volume pedestrian use. The extra duty arm provides added resistance to abuse and forced-open conditions common in high-traffic corridors. Contractors and door hardware installers typically specify this unit on hollow metal and solid wood door frames.

Installation Notes

Installation is performed by a licensed door hardware technician or commercial carpenter following the manufacturer's template. Confirm door and frame construction can support the closer body and arm fastener pattern before drilling. All fasteners should be driven into solid substrate; hollow-core blocking may be required on wood doors. Verify final closing speed, latch speed, and delayed-action timing adjustments with the door under normal traffic load before completing the installation.
