Gibraltar 428-1080 Soft Vise Jaw 6 Inch Flat Fixed

Product Description

The GIBRALTAR 428-1080 is a flat, fixed soft vise jaw designed for use with 6-inch vises in machine shop, fabrication, and toolroom environments. Constructed from aluminum, this jaw measures 6 inches wide, 4 inches high, and 2 inches thick, providing a substantial gripping surface that protects finished or soft workpieces from marring during clamping. The soft jaw design absorbs clamping pressure without transferring it as surface damage to the part being held. At 9.689 pounds, it offers solid mass for stable fixturing. Machinists, tool and die makers, and fabricators install this type of jaw as a direct replacement or upgrade on compatible bench vises.

This jaw is suited for machine shop benches, manufacturing floors, and maintenance shops where workholding precision matters. The fixed jaw movement type makes it appropriate for stationary mounting on the fixed side of a 6-inch vise. The flat jaw profile works well with square stock, plate, and flat-sided workpieces. It is a practical choice wherever metal-to-metal contact between a steel vise jaw and a finished or soft-material workpiece would cause unacceptable surface damage.

Compatibility

Designed for use with 6-inch vises. Verify bolt pattern and mounting dimensions against the target vise before installation.

Installation Notes

Installation is typically performed by a machinist or tool room technician. Before replacing or installing vise jaws, fully release clamping pressure and secure the vise in a stable position. Use fasteners appropriate to the vise manufacturer's jaw mounting specification and ensure the jaw seats flush before applying torque. Inspect the mating surfaces on the vise body for burrs or debris that could prevent full seating of the replacement jaw.
