ABH 1023 US32D Concealed Overhead Stop | Heavy Duty

The ABH 1023 US32D is a premium, high-performance concealed overhead stop designed for architectural aesthetics and rigorous door control. Engineered for a 36-inch opening, this heavy-duty device is the definitive solution for door restoration in high-traffic environments where floor or wall stops are impractical or unsightly. By being mortised into the top rail of the door and the head of the frame, the 1023 model remains completely invisible when the door is closed, providing a clean, modern solution for commercial door security.

Heavy-Duty Protection for Frequent Traffic

The ABH 1000 series is built to withstand the daily abuse of institutional and commercial use, protecting your investment in hardware and infrastructure:

• Shock Absorbing Spring: Features a heavy-duty internal spring that provides a 3° to 5° cushion before reaching a firm dead-stop, preventing sudden jolts that damage hinges and pivots.
  
• Frequent Traffic Rated: Specifically designed for interior or exterior doors subjected to constant operation, acting as a permanent solution for door surface repair by eliminating impact damage to walls and frames.
  
• Non-Handed Design: Fully reversible for use on single or double-acting doors, providing maximum flexibility during site installation.
  
• Architectural Finish: Crafted from high-grade stainless steel with a US32D (Satin Stainless) finish, ensuring long-term corrosion resistance in even the most demanding environments.
  

Versatile Sizing and Compliance

The ABH 1023 is precision-sized to fit specific door opening ranges, ensuring the leverage and stopping power are perfectly tuned to the door's width:

• Hinges/Offset Pivots: Fits door frame openings from 36" thru 39-15/16" wide.
