The JACKNOB 770-PC is a gravity hinge designed for left-hand inswing door applications. Gravity hinges use the weight of the door and a cam-based pivot mechanism to automatically return a door to a closed position without the need for a separate door closer. Sold as a pair, this unit provides the complete top and bottom pivot set required for a full installation. Gravity hinges of this type are commonly specified in restroom partition and commercial door applications where hands-free, self-closing operation is required.
This hinge pair is suited for left-hand inswing door configurations in commercial and light-industrial environments. Typical installations include toilet partition doors, bathroom stall entries, and similar interior applications where self-closing door hardware is required by building or accessibility codes. Installation is performed by a carpenter, millwork contractor, or general trades professional familiar with door hardware.
Designed as an OEM-style replacement or new-installation gravity hinge for left-hand inswing interior commercial doors and partition assemblies.
Installation is typically performed by a qualified carpenter or door hardware technician. Ensure the door panel is properly supported before removing any existing hardware. Follow the door manufacturer's recommended mounting specifications and any applicable local building code requirements for self-closing hardware. Verify left-hand inswing orientation before installation to confirm correct hinge selection.
