ABH 4434 Surface Mounted Friction Hold-Open Overhead Door Stop | US32D Satin Stainless Steel

The ABH 4434 is an architectural-grade, medium-duty surface mounted overhead door stop featuring a specialized friction hold-open mechanism designed for wide commercial openings. Sized for doors between 36" and 48" wide, this hardware is a premier solution for door restoration, engineered to protect the structural integrity of oversized doors, frames, and hinges. Finished in premium US32D Satin Stainless Steel, the 4434 model provides a robust solution for commercial door security and wall protection in large corridors, hospital wings, and educational facilities.

Adjustable Tension for High-Traffic Wide Openings

The ABH 4434 is optimized for extra-wide doors, 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 wide door leaves:

• Customizable Friction Hold-Open: Unlike fixed-point stops, the friction mechanism allows the door to be held open at any desired position along its swing. The tension is easily adjustable to resist drafts or heavy traffic, helping your facility meet ADA requirements for accessible, hands-free passage.
  
• Field Adaptable Functionality: This multi-functional unit offers maximum versatility. The friction hold-open feature can be disengaged on-site to act as a Stop Only function, providing a flexible solution for door restoration as room usage evolves.
  
• Shock-Absorbing Spring: Features an internal shock-absorbing spring that provides a 3° to 5° cushion before the dead stop, significantly reducing the mechanical stress on the door frame and hinges during forceful openings.
  
• Non-Handed & Reversible: The 4434 is completely non-handed, making it a reliable stock item for facility managers because it installs seamlessly on both left and right-hand doors.
  

Industrial-Grade Stability with Thru-Bolt Engineering

Overhead hardware on wide doors is subject to extreme stress. The ABH 4434 is built to remain secure and stable for the life of the opening:

• High-Strength Thru-Bolt Mounting: To ensure the unit stays rigid and never pulls loose from the door face, it is installed using thru bolts (included). This "clamping" method provides superior stability over standard screws, serving 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 4434 is built to endure the rigors of institutional use without mechanical fatigue.
• Warnock Hersey Listed: In its "Stop Only" configuration, this hardware is Warnock Hersey listed, meeting the stringent fire and life safety standards required for modern commercial buildings.
• 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.
