ABH 4432 Surface Mounted Friction Hold-Open Overhead Door Stop | US32D Satin Stainless Steel

The ABH 4432 is a professional-grade, medium-duty surface mounted overhead door stop featuring a specialized friction hold-open mechanism. Sized specifically for medium-width door openings, this hardware is a premier solution for door restoration that allows a door to be held open at a desired position through adjustable tension. Crafted from high-grade stainless steel, the 4432 model provides a robust solution for commercial door security and wall protection in office buildings, schools, and healthcare facilities.

Adjustable Tension for Versatile Medium Openings

The ABH 4432 is engineered to provide precise control for mid-sized doors, allowing facility managers to manage traffic flow and prevent impact damage. It acts as a proactive solution for door surface repair by regulating the door's swing with mechanical reliability:

• Customizable Friction Hold-Open: The friction mechanism allows the door to remain open at a specific point without the "click" of a standard hold-open. The tension can be adjusted to resist light drafts or heavy traffic, assisting facilities in meeting ADA requirements for accessible passage.
• Field Adaptable Functionality: This unit is designed for flexibility. The friction hold-open feature can be disengaged on-site to convert the unit into a Stop Only function, providing a versatile solution for door restoration as room requirements change.
  
• Precise Stop Increments: The stop/hold-open position is adjustable in 5-degree increments from 85° to 110°, allowing you to protect expensive wall-mounted equipment or millwork by stopping the door at a safe angle.
  
• Non-Handed & Reversible: The 4432 is completely non-handed and reversible, ensuring a straightforward installation on both left and right-hand doors and simplifying maintenance inventory.
  

Industrial-Grade Stability with Thru-Bolt Engineering

Overhead hardware on medium-width doors is subject to significant leverage. The ABH 4432 is built to remain stable and secure through years of constant operation:

• 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 "sandwich" style mounting provides superior stability over standard screws, serving as a permanent solution for door edge reinforcement.
• Architectural Satin Stainless Steel: Finished in US32D (630), the 3/4” wide stainless steel channel and 3/16” thick arm are highly resistant to corrosion and the aggressive cleaning chemicals common in institutional settings.
• 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 architecture.
• Precision Sliding Block: The internal mechanism utilizes a high-durability sliding block within the channel to ensure smooth, quiet, and consistent friction throughout the product's lifespan.
