Wilton A-4.5 Magnefix Aluminum Jaw Caps have a six-groove design to firmly grasp and hold workpieces with irregular surfaces. These authentic replacement caps are designed to protect both the vise jaws and the workpiece from marring and distortion during any clamping application.

• Caps are constructed from a hardened aluminum alloy with two built-in circular permanent magnets on the backside which holds the product securely to the vise
• Caps are magnetic towards the vise side to prevent steel filings from attaching themselves to the jaws and keep the clamped part from becoming magnetized
• Deeper V-groove ensures more secure clamping of circular workpieces
• 4.5 in jaw opening
