Hadrian 640004 Lower Door Casting | Commercial Partition Hinge Component

The Hadrian 640004 Lower Door Casting is a critical structural element designed for the bottom hinge assembly of commercial toilet partition doors. This heavy-duty metal casting serves as the housing for the internal cam system, which controls the door's self-closing or self-opening resting position. It is the premier solution for door restoration when a restroom stall door becomes misaligned, sags, or fails to pivot smoothly, allowing for a targeted repair without the expense of a full door replacement.

To ensure a perfect match for your existing hardware, this genuine Hadrian part is identified by the part number 410004 stamped inside the metal casting. Replacing a cracked or worn lower casting with the 640004 is an essential solution for door security and privacy, as it restores the structural integrity of the main weight-bearing pivot point in the partition system.
