Don-Jo 1512 Commercial Hinge Pin Stop | For 4.5" Architectural Hinges

The Don-Jo 1512 Commercial Hinge Pin Stop is a heavy-duty door control solution designed specifically for high-traffic industrial and commercial environments. Unlike standard residential hardware, this 4.5-inch hinge pin stop is engineered to withstand the weight and force of heavy architectural doors. It provides a reliable way to limit door swing without the need for floor or wall-mounted stops, making it the perfect solution for commercial door protection in hallways, offices, and utility rooms.

This professional-grade stop is fully adjustable, allowing you to set the maximum door opening from 95 degrees to 120 degrees. This precision ensures that your lever handles and exit devices do not impact adjacent walls, glass sidelights, or furniture.

Key Features & Performance

• Industrial Compatibility: Specifically manufactured for commercial 4.5" architectural hinges. Note: This model is not intended for use with smaller residential hinge sizes.
  
• Non-Marring Design: Engineered to protect your facility's aesthetics; it will not mar or mark the door or frame, ensuring your paint and wood finishes remain pristine over time.
  
• Adjustable Swing Range: Offers a customizable stop from 95 degrees to 120 degrees, providing flexibility for unique room layouts and tight corners.
