Hadrian 640003 Upper Door Casting | Commercial Partition Hinge Component

The Hadrian 640003 Upper Door Casting is a critical structural component designed for the top hinge assembly of commercial toilet partition doors. This heavy-duty metal casting is engineered to provide a secure pivot point, ensuring the door remains perfectly aligned during thousands of open-and-close cycles. It is the premier solution for door restoration when a restroom stall door begins to sag or binds at the top, allowing facility managers to restore factory-level performance without replacing the entire door leaf.

For easy identification and compatibility matching, this casting features part number 410003 stamped inside the metal. Whether you are performing a routine maintenance upgrade or an emergency repair, the 640003 acts as a permanent solution for door security by maintaining the structural integrity of the upper pivot point, preventing unauthorized door removal and ensuring user privacy.

Key Features & Performance

• Precision Pivot Engineering: Designed to house the upper hinge pin, providing a low-friction rotation point that serves as a high-performance solution for door restoration.
• Internal Part Identification: Verified by the internal stamp 410003, ensuring a guaranteed fit for Hadrian-brand restroom partitions and eliminating guesswork during the ordering process.
• Heavy-Duty Construction: Manufactured from high-strength cast metal to withstand the lateral stress of heavy partition doors, acting as a durable solution for door edge reinforcement.
• Vandal-Resistant Mounting: Designed for use with specialized security fasteners, making it a reliable remodeling scar plate for hinge areas that have been loosened by heavy use or tampering.
• Seamless Integration: Works in conjunction with the lower gravity-cam system to provide a balanced, self-closing or self-opening door action.
