Heavy Duty Commercial Door Closer for Dynasty Series 8500-HO

The Dynasty Hardware 8500 series aluminum door closer is a non-handed unit designed for regular arm, top-jamb, or parallel arm installation. This commercial-grade, Grade 1 automatic door closer with a hold-open arm is an excellent quality closer that complies with the Americans with Disabilities Act (ADA) and encompasses all levels of ANSI classification, grades 1, 2, and 3, as well as UL requirements.

The 8500 series door closer uses the same hole pattern as the Norton 8501 and 8301 door closers, making it a perfect replacement. It is a non-sized door closer that can be set from size 1 through 6, with the factory preset to size 3. This hydraulic door closer comes standard with a back-check function and offers adjustable closing and latching speed through two separate regulating valves.

The closer is tri-packed with wood screws, metal screws, and through-bolts for fire-rated doors. It is adjustable from size 1 through 6 to fit doors weighing 40 to 240 pounds. The Dynasty Hardware 8500 series door closer can be mounted in a regular arm, parallel arm, or top-jamb configuration, and each unit includes a parallel arm bracket and all necessary fasteners for installation.

The friction-style hold-open arm on the 8500 series door closer allows the door to be held open between 90 and 180 degrees, and the hold-open can be easily released by simply pulling the door shut. The screw hole spacing for this door closer is 12 inches center-to-center for the horizontal mounting holes and 3/4 inch center-to-center for the vertical screw holes.

The Dynasty 8500 series door closer is a direct replacement for the Norton 8301-H, 8501-H, Yale 3301, and 3501 door closers. It features two adjustment valves: one for the closing speed and one for the latching speed. An allen wrench for adjusting the door closer is included.

The Dynasty Hardware 8500 series door closer also offers an adjustable back-check valve, which controls the amount of resistance to opening the door past a selected point. This feature helps control the door's opening speed to protect walls from potential damage caused by sudden, forceful opening.

In summary, the Dynasty Hardware 8500 series commercial-grade automatic door closer with a hold-open arm is a versatile, ADA-compliant, and high-quality closer that can be easily installed and adjusted to meet a wide range of door-opening requirements.
