Gibraltar 428-1072 Soft Vise Jaw 8 Inch Flat Fixed Aluminum

Product Description

The GIBRALTAR 428-1072 is a flat, fixed soft vise jaw designed as a direct replacement jaw for 8-inch bench vises. Machined from aluminum, this jaw measures 8 inches wide, 2.5 inches high, and 1.25 inches thick. The soft aluminum construction protects finished or delicate workpiece surfaces from marring, denting, or scoring during clamping operations. It is a fixed jaw configuration, meaning it mounts to the stationary jaw face of the vise. Machinists, tool-and-die workers, fabricators, and maintenance technicians install this type of jaw when grip protection is the priority over raw clamping aggression. At 5.047 pounds, this is a solid, full-width replacement.

This jaw is suited for use in machine shops, fabrication shops, and maintenance environments where workholding on an 8-inch bench vise is routine. The flat jaw profile handles stock, bar, plate, and shaped workpieces that require even clamping across the full jaw face. It is appropriate for both production and toolroom settings. The aluminum material makes it a practical choice when clamping softer metals, plastics, or pre-finished parts where steel jaw faces would cause surface damage.

Key Features

• Soft aluminum construction protects workpiece surfaces from jaw marks and deformation
• Flat jaw profile provides even clamping pressure across the full 8-inch width
• Fixed jaw design for mounting to the stationary jaw face of compatible vises
• 8 inches wide by 2.5 inches high by 1.25 inches thick for a full-coverage replacement fit
• Lightweight aluminum reduces added mass to the vise assembly

Compatibility

Designed as a replacement soft jaw for 8-inch bench vises. The supplier data specifies compatibility with 8-inch vises as a product class.

Installation Notes

Soft vise jaws are typically installed by machinists or maintenance technicians using standard hand tools. Power down any associated equipment and secure the vise before removing existing jaw hardware. Follow the vise manufacturer fastener pattern and torque guidance as specified in their service documentation. Do not overtighten fasteners into the aluminum jaw body, as the material is softer than steel and threads can strip if excessive force is applied.
