The ABH 4412 is a professional-grade, medium-duty surface mounted overhead door stop designed to provide a comprehensive solution for commercial door security and maintenance. Specifically sized for medium-width openings, this hardware protects your door, hinges, and adjacent walls from the damaging effects of over-extension. Featuring a high-quality US32D Satin Stainless Steel finish, the 4412 model is the definitive solution for door restoration in high-traffic hallways, classrooms, and office suites.

Versatile Functionality for Professional Facilities

The ABH 4412 is engineered for flexibility, allowing facility managers to customize door behavior based on specific room requirements. It serves as a proactive solution for door surface repair by controlling the door's maximum swing:

• Automatic Hold-Open & Release: The internal sliding block mechanism allows the door to engage or release the hold-open position simply by a firm push or pull. This hands-free operation supports ADA requirements and streamlines traffic in busy environments.
• Field Adaptable Functions: This unit is multi-functional. The hold-open feature can be easily disengaged in the field to convert the unit into a Stop Only function, providing a versatile solution for door restoration if safety requirements change.
• Customizable Stop Points: The single-point hold-open is adjustable in 5-degree increments from 85° to 110°, ensuring the door stops exactly where you need it to protect furniture or wall-mounted equipment.
  
• Non-Handed & Reversible: The 4412 is completely non-handed, making it a reliable stock item for maintenance teams as it can be installed on both left and right-hand doors without modification.
  

Heavy-Duty Construction & Thru-Bolt Stability

Stability is paramount for overhead hardware. The ABH 4412 is built to absorb repeated shock and remain securely fastened to the door and frame:

• High-Strength Thru-Bolt Mounting: To ensure the hardware never pulls loose or sags under stress, this unit is installed using thru bolts (included). This "clamping" method provides superior stability compared to standard surface screws, acting as a robust solution for door edge reinforcement.
• Architectural Grade Materials: Featuring a 3/4” deep stainless steel channel and a solid 3/16” thick arm, the 4412 is built to endure the rigors of institutional use while maintaining its aesthetic appeal.
• Warnock Hersey Listed: When configured as a "Stop Only" unit, this hardware is Warnock Hersey listed, meeting strict fire and life safety standards for manufactured door components.
• Smooth Sliding Mechanism: The hold-open mechanism utilizes a precision-engineered sliding block for a consistent, reliable feel throughout the life of the product.
