The GIBRALTAR 428-1079 is a flat, fixed soft vise jaw designed as a replacement or spare jaw for 6-inch bench vises. Machined from aluminum, this jaw measures 6 inches wide, 2 inches high, and 2 inches thick, providing a broad clamping surface that protects finished or delicate workpieces from marring. The soft aluminum construction absorbs clamping force without transferring hard edges to the part being held. Machinists, tool-and-die technicians, and fabricators install this jaw when working on parts that require a secure hold without surface damage.
This jaw is suited for use in machine shops, maintenance facilities, and fabrication environments where a standard hard-jaw vise needs to be converted to soft-jaw duty. It is designed for fixed-jaw position use on 6-inch vises and is commonly installed on bench vises used for milling setups, assembly work, and general metalworking applications where part protection is a priority.
Designed for use with 6-inch bench vises. Verify jaw slot dimensions against the existing vise before installation to confirm fitment.
Installation is typically performed by a machinist or maintenance technician. Secure the vise in a stationary position before removing existing jaws, and ensure all fasteners are fully seated before applying clamping loads. Do not exceed the rated capacity of the host vise. Refer to the vise manufacturer's instructions for jaw replacement procedures.
