Magnetic Jaw Caps for 4.5 Inch Vises

These aluminium caps fit any vise with a 4.5 inch jaw width. They protect both the vise jaws and the workpiece from marring and distortion during clamping. The magnetic backing holds each cap securely in place. The pack contains two caps for a complete jaw set.

Installation and Common Issues

Each cap snaps onto the jaw face by magnetic attraction, requiring no bolts or adhesives. The most frequent issue is debris between the magnet and the vise jaw, which reduces holding force; wiping both surfaces clean before fitting prevents this. Aluminium is softer than steel jaws, so the caps will wear over time and should be inspected regularly.

Suitability and Limitations

Machinists and fabricators who need to clamp finished or soft materials without marking them will benefit from these caps. They are not suited for users who require hardened jaw faces for heavy material removal or high-pressure clamping where the aluminium could deform. Buyers needing jaw widths other than 4.5 inches must select a different size.

Questions about this item

How do I confirm the magnetic jaw caps are holding securely after placing them on my 4.5 in vise jaws?

The caps should snap firmly onto the 4.5 in jaws and stay in position without shifting; run a test clamp on a scrap piece to verify the workpiece does not mar or slip.

What comes in the package and do I need to buy mounting hardware separately?

The box contains two aluminum magnetic jaw caps sized for 4.5 in vise jaws; no additional hardware is required because the caps attach magnetically.

Which version of the Wilton A-4.5 should I choose for a 4.5 in vise?

The A-4.5 model is made specifically for 4.5 in vise jaw widths, so select this version when your vise measures 4.5 in across the jaws.
