Gibraltar 428-1061 Soft Vise Jaw 4.125in Flat Aluminum

Product Description

The GIBRALTAR 428-1061 is a flat soft vise jaw designed as a fixed replacement jaw for bench vises. Machined from aluminum, this soft jaw protects workpiece surfaces during clamping by reducing the risk of marring or deforming finished or delicate materials. It measures 4.125 inches wide, 1.5 inches high, and 1 inch thick, fitting standard 4-inch vises. Machinists, toolmakers, and general fabrication professionals install this jaw when gripping parts that require a softer contact surface than hardened steel jaws provide.

This jaw is suited for use in machine shops, fabrication facilities, and maintenance environments where workpiece protection is a priority. The flat jaw profile handles square stock, flat plate, and similar geometry. As a fixed jaw replacement, it mounts to the stationary side of a compatible bench vise. The aluminum construction keeps weight low while providing adequate clamping surface rigidity for light to moderate holding applications.

Key Features

• Soft aluminum construction protects finished or delicate workpiece surfaces from marring
• Flat jaw profile provides full-face contact on square and flat stock
• Fixed jaw design for installation on the stationary vise jaw position
• 4.125 inches wide by 1.5 inches high face provides a broad clamping surface

Compatibility

Designed for use with 4-inch bench vises. Confirm mounting hole pattern and jaw profile match your specific vise model before installation.

Installation Notes

Installation is typically performed by a machinist or maintenance technician. Fully release vise clamping pressure and secure the vise to a stable work surface before removing the existing jaw. Use appropriately sized fasteners and a calibrated torque driver per the vise manufacturer specifications. Inspect mounting surfaces for debris or damage before seating the new jaw.
