Commercial Grade Hydraulic Adjustable Spring Door Closer Series 4401

Product Description The Dynasty Hardware 4401 Series Commercial Grade 1 Automatic Door Closer is a high-quality, heavy-duty door closer suitable for commercial use. It is non-handed, allowing for installation in regular arm, top-jamb, or parallel arm configurations. This barrier-free closer is designed to meet ADA regulations and ANSI classification grades 1, 2, and 3, as well as UL requirements.

This door closer uses the same hole pattern as the LCN 4040 and LCN 4010 models, making it a perfect replacement option. It is non-sized but can be adjusted from size 1 thru 6 (preset to size 3 from the factory) to fit doors weighing between 40 to 240 pounds. The hydraulic door closer comes with a back-check function and offers adjustable closing and latching speed through two regulating valves.

Tri-packed with wood screws, metal screws, and thru-bolts for fire-rated doors, this door closer is versatile and easy to install. It features full plastic cover and is designed with reduced spring power to facilitate easier opening for handicapped or elderly individuals. The Dynasty Hardware 4401 Series Door Closer also includes adjustable sweep and latch valves for added customization.

Featuring two adjustment valves, this door closer allows for precise control over the closing and latching speed. The included allen wrench makes adjustments easy and convenient. Additionally, the adjustable back-check valve enables users to regulate the resistance when opening the door past a certain point, providing protection against potential damage to walls.

The Dynasty Hardware 4401 Series Door Closer offers multiple mounting options, including regular arm, parallel arm, and top jamb configurations. It comes with a parallel arm bracket and all necessary fasteners for installation. With its grade 1 ANSI 156.4 heavy-duty rating and UL listing for fire door assemblies, this door closer is a reliable and durable choice for commercial applications.
