Gibraltar 428-1070 Soft Vise Jaw 8.125in Flat Fixed Aluminum

Product Description

The GIBRALTAR 428-1070 is a flat, fixed soft vise jaw designed as a direct replacement or upgrade jaw for 8-inch bench vises. Machined from aluminum, this jaw measures 8.125 inches wide, 2.5 inches high, and 1 inch thick, making it a proper fit for standard 8-inch vise bodies. The soft aluminum construction protects finished or delicate workpieces from marring and crushing during clamping operations. This type of jaw is a standard consumable in machine shops, fabrication environments, and maintenance facilities where protecting workpiece surfaces is a daily requirement. The fixed jaw design means it mounts to the stationary jaw body of the vise.

The 428-1070 is suited for use in machine shops, toolrooms, and industrial maintenance settings where an 8-inch vise is the primary workholding device. The flat jaw profile accommodates parallel-sided stock and flat workpieces. Machinists, millwrights, and maintenance technicians typically keep soft jaw sets on hand to swap in whenever a job calls for non-marring clamping. The aluminum material is soft enough to conform slightly under clamping load, which helps distribute pressure evenly across the workpiece face.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with vise jaw changeout procedures. Remove any existing jaw hardware and clean the jaw mounting surface before installing the new jaw. Secure mounting fasteners evenly to ensure full contact across the jaw face. Verify jaw seating before returning the vise to service.
