ABH 4424 Surface Mounted Overhead Door Stop | US32D Satin Stainless Steel

The ABH 4424 is an architectural-grade, medium-duty surface mounted overhead door stop specifically designed for wide door openings. This hardware is a critical solution for door restoration, engineered to protect the structural integrity of oversized doors, frames, and hinges by controlling the door's maximum swing. Finished in premium US32D Satin Stainless Steel, the 4424 model is the premier solution for commercial door security in large corridors, hospital wings, and educational facilities.

Adaptive Performance for Extra-Wide Openings

The ABH 4424 is optimized for openings up to 48" wide, providing heavy-duty control where standard stops fail. It acts as a proactive solution for door surface repair by absorbing the high leverage forces generated by wider door leaves:

• Field Adaptable Functionality: This multi-functional unit offers maximum flexibility. While it features an automatic hold-open mechanism, it can be easily disengaged on-site to act as a Stop Only function, providing a versatile solution for door restoration as facility needs evolve.
• Automatic Hold-Open & Release: The precision internal sliding block engages and releases the door with a simple, firm push or pull. This hands-free operation is essential for meeting ADA requirements and facilitating movement in high-traffic service areas.
• 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, furniture, or exit signs by stopping the door at a precise angle.
  
• Universal Non-Handed Design: The 4424 is completely non-handed and reversible, ensuring a seamless installation on both left and right-hand doors, which simplifies inventory for facility maintenance teams.

Industrial-Grade Stability with Thru-Bolt Engineering

Overhead hardware on wide doors is subject to extreme stress. The ABH 4424 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 under the weight of a 4-foot door, 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 Stainless Steel Construction: Featuring a 3/4” wide stainless steel channel and a solid 3/16” thick arm, the 4424 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 manufactured door components.
• Satin Stainless Steel (US32D): The finish is not only aesthetically pleasing but also provides a durable, corrosion-resistant layer that withstands harsh cleaning agents used in medical and educational environments.
