The LCN 4041-DEL-REG-689 is a heavy-duty surface-mounted door closer engineered for demanding commercial and institutional openings. Built around LCN's durable cast iron body, it offers an adjustable spring size of 1 through 6, making it suitable for a wide range of door widths and traffic conditions. This model features a regular arm for standard pull-side mounting, delayed action control for slower closing, and an aluminum painted (689) finish. Non-handed and shipped with a plastic cover, it installs on push or pull side applications and delivers up to 120 degrees of door swing. As a Grade 1 closer, it meets the reliability standards expected in schools, hospitals, offices, and other high-use environments.

Features

• Adjustable spring size 1 through 6 covers a broad range of door sizes and applications.
• Delayed action provides a slower, controlled closing cycle for accessibility and high-traffic use.
• Regular arm configuration supports standard pull-side mounting.
• Non-handed design fits both left- and right-hand doors.
• Push or pull side mounting flexibility simplifies specification and installation.
• Durable cast iron body withstands heavy commercial cycling.
• Aluminum painted (689) finish blends with most door and frame hardware.
• Plastic cover included for a clean, finished appearance.

Functional Details

The delayed action feature slows the closing speed during the initial portion of the cycle, giving pedestrians, carts, or those with mobility needs extra time to pass through before the door begins to close normally. Separate valves allow independent adjustment of closing speed, latch speed, and back check.

• Separate regulating valves control closing speed, latch speed and backcheck
• Delayed action provides additional closing time
• Sizeable spring power adjustment (sizes 1 through 6)

Arm Type Details

This closer uses the standard regular arm, a surface-mounted double-lever arm designed for pull-side installation. It projects from the door and provides efficient, reliable closing force for typical interior and exterior openings.

Included Components

Ships with the closer body, regular arm assembly, mounting hardware, and a plastic cover.
