Accentra 2721 Grade 1 Heavy-Duty Door Closer with Rigid Parallel Stop Arm
The Accentra 2721 Heavy Duty Door Closer (formerly the Yale 2700 Series) is a high-intent, architectural-grade solution specifically engineered for maximum protection in high-abuse and high-traffic environments. This model is defined by its Rigid Parallel Arm with Removable Stop, which provides a physical mechanical "dead stop" to prevent the door from swinging past a predetermined degree. By integrating the stop directly into the closer arm, the 2721 eliminates the need for separate overhead or floor stops, protecting your door, hinges, and adjacent walls from costly structural damage.
As part of the premium 2700 Series, the 2721 combines rugged, industrial-strength construction with a sleek, professional aesthetic. It is the ideal choice for exterior entrances, school corridors, and retail spaces where heavy wind loads or frequent use often lead to over-extended doors.
Advanced Mechanical Protection & Control
- Rigid Stop Arm (Push Side): The heavy-duty parallel arm features a removable stop that prevents the door from over-extending. This protects the opening during violent gusts of wind or forceful openings by pedestrians.
- Fully Adjustable Spring Power (Sizes 1–6): The adjustable spring tension allows for precise tuning. Set it to a low opening force for ADA accessibility on interior doors or maximize the power to secure heavy exterior perimeter doors.
- Triple Valve Precision: Equipped with three independent, non-critical valves to customize Closing Speed, Latching Speed, and Backcheck. The Backcheck valve is especially critical in this model, as it provides hydraulic cushioning before the door reaches the mechanical stop.
- Grade 1 Industrial Strength: Certified ANSI/BHMA A156.4 Grade 1, rigorously tested for over a million cycles to ensure long-term reliability in the most demanding commercial settings.
- Universal Handing: The non-handed design simplifies installation, allowing the closer to be mounted on both left and right-hand door swings without modification.
