PBB WT4B81-4 1/2" x 6" NRP Wide Throw Steel Full Mortise Heavy Weight Hinge, 5 Knuckle Ball Bearing, 4 1/2" High, x 6" With" NRP" Non Removable Pin

The PBB WT4B81 hinge measures 4.5" by 6" and features a wide throw design crafted from steel for heavy-duty applications. This full mortise hinge includes a 5-knuckle ball bearing mechanism and a non-removable pin, ensuring durability and security. Its dimensions are 4.5" in height by 6" in width, making it suitable for robust door installations.

  • For use on heavy-weight doors requiring high-frequency service.
  • For use where doors must clear molding or protrusion, positioning the door out further, when open.
  • All hinges are ANSI templates.
  • The screw pack includes all machine screws (24), and 1/2 wood screws (12). 

Purpose:
Wide throw hinges are used to maximize door swing clearance, making them ideal for healthcare environments where unobstructed access is critical.

Functionality:
These hinges feature an extended pivot point that moves the door farther away from the frame as it opens, allowing it to swing a full 180 degrees. This design significantly increases the clear opening width compared to standard hinges.

Applications in Healthcare:
In hospital patient rooms, wide throw hinges are handy for accommodating the movement of wheelchairs, hospital beds, and medical equipment. They ensure that doors can open fully and lie flat against the wall, minimizing obstructions and facilitating smooth patient transfers and emergency access.

Comparison to Swing Clear Hinges:
While swing clear hinges also increase the clear opening by shifting the door out of the frame’s path, they typically allow for a 90-degree swing. Wide throw hinges, on the other hand, enable a full 180-degree swing, offering greater accessibility—critical in critical care or ADA-compliant environments.

Example:
For example, in a patient room with wide casing or recessed door frames, a wide throw hinge allows the door to swing completely open, ensuring enough clearance for a hospital bed to be easily rolled in or out without striking the door or frame.
