Adjustable Spring Door Closer Series 4401 for Commercial Use

The Dynasty Hardware 4401 series aluminum door closer is a commercial grade heavy-duty door closer that is non-handed for regular arm, top-jamb, or parallel arm installation. This door closer is an excellent quality closer designed to comply with the Americans with Disabilities Act (ADA) and encompass all levels of ANSI classification, grades 1, 2, and 3, as well as UL requirements.

The 4401 series door closer features a hydraulic design with a standard adjustable back-check function, offering adjustable closing and latching speed by two separate regulating valves. It is a non-sized closer that can be set from size 1 through 6, with the factory preset size being 3. This door closer is suitable for doors weighing 40 to 240 pounds.

The door closer comes tri-packed with wood screws, metal screws, and through-bolts for fire-rated doors. It has a full plastic cover and is designed to be barrier-free, meeting ADA regulations. The reduced spring power makes the door easier to open for handicapped or elderly individuals.

The adjustable back-check valve controls the amount of resistance to opening the door past a selected point, helping to protect walls from damage if the door is thrown open or caught by the wind. The back-check feature is used to slow the door down, not to stop it.

The Dynasty Hardware 4401 series door closer can be mounted in a regular arm, parallel arm, or top-jamb configuration. Each closer includes a parallel arm bracket and all the necessary fasteners for installation. The closer body mounting hole pattern matches the LCN 4040 and 4010 models, making it a perfect replacement option.

In summary, the Dynasty Hardware 4401 series door closer is a commercial-grade, heavy-duty, and ADA-compliant closer that offers a range of adjustable features and mounting options, making it a versatile and reliable choice for various door applications.
