Gibraltar 428-1063 Soft Vise Jaw 4.125in Flat Aluminum

Product Description

The GIBRALTAR 428-1063 is a flat soft vise jaw replacement designed for use with 4-inch bench vises. Machined from aluminum, this fixed jaw measures 4.125 inches wide, 1.75 inches high, and 0.75 inches thick, providing a consistent clamping surface without marring or damaging workpiece surfaces. Soft jaws are a standard replacement component in machine shops, fabrication environments, and maintenance facilities where protecting finished or delicate materials during clamping is a priority. At 0.97 pounds, it is lightweight and straightforward to install on compatible vises.

This jaw is suited for bench vise applications in industrial, manufacturing, and trade shop settings where a flat clamping profile is required. The fixed jaw configuration makes it a direct replacement for worn or damaged original jaws on 4-inch vises. It is appropriate for machinists, toolmakers, maintenance technicians, and fabricators who require a non-marring jaw surface. The aluminum construction keeps weight low while providing adequate clamping support for general workholding tasks.

Compatibility

Designed as a replacement soft jaw for 4-inch bench vises. Verify jaw mounting hole pattern and overall dimensions against existing hardware before installation.

Installation Notes

Installation is typically performed by a machinist or maintenance technician. Before replacing vise jaws, fully release vise pressure and secure the vise to a stable work surface. Use appropriate fasteners to match the existing mounting pattern on the vise body. Do not overtighten fasteners, as aluminum jaw material may deform under excessive clamping force at the mounting points.
