ABH 4422 Surface Mounted Overhead Door Stop | US32D Satin Stainless Steel

The ABH 4422 is a professional-grade, medium-duty surface mounted overhead door stop designed specifically for medium-width door openings. This architectural hardware is a critical solution for door restoration, engineered to prevent damage to the door, frame, and adjacent walls by controlling the door's swing. Finished in high-quality US32D Satin Stainless Steel, the 4422 model serves as a premier solution for commercial door security and long-term facility protection.

Versatile Functionality for Institutional Environments

The ABH 4422 offers maximum field flexibility, allowing maintenance teams to customize the hardware based on specific traffic patterns. It acts as a proactive solution for door surface repair by absorbing the shock of over-extension:

• Automatic Hold-Open & Release: The precision sliding block mechanism allows the door to engage or release the hold-open position with a simple push or pull. This hands-free operation supports ADA requirements and facilitates easy movement in busy office or clinical settings.
• Field Adaptable Functions: This multi-functional unit can be easily modified on-site. The hold-open feature can be disengaged to convert the hardware into a Stop Only function, providing a versatile solution for door restoration as room usage evolves.
• Customizable Stop Points: The single-point stop/hold-open can be adjusted in 5-degree increments from 85° to 110°, allowing you to protect wall-mounted equipment or furniture by stopping the door at a precise angle.
  
• Non-Handed & Reversible: The 4422 is completely non-handed, making it a reliable stock item for facility managers because it installs seamlessly on both left and right-hand doors.
  

Heavy-Duty Construction & Thru-Bolt Stability

Stability is essential for overhead hardware subjected to constant use. The ABH 4422 is built to remain secure and stable for the life of the opening:

• High-Strength Thru-Bolt Mounting: To ensure the hardware never pulls loose or sags, this unit is installed using thru bolts (included). This "clamping" method provides superior stability compared to standard surface screws, acting as a permanent solution for door edge reinforcement.
• Architectural Grade Materials: Featuring a 3/4” wide stainless steel channel and a solid 3/16” thick arm, the 4422 is built to endure the rigors of institutional use without mechanical fatigue.
• Warnock Hersey Listed: In the "Stop Only" configuration, this hardware is Warnock Hersey listed, ensuring it meets the stringent fire and life safety standards required for modern commercial buildings.
• Satin Stainless Steel (US32D): The finish is not only aesthetically pleasing for modern interiors but also provides a durable, corrosion-resistant layer that withstands harsh cleaning agents.
