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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSoft aluminum construction protects workpiece surfaces from marring during clamping\u003c\/li\u003e\n  \u003cli\u003eFlat jaw profile provides uniform contact across the clamping face\u003c\/li\u003e\n  \u003cli\u003eFixed jaw type for direct OEM-style replacement\u003c\/li\u003e\n  \u003cli\u003eSized for compatibility with 4-inch bench vises\u003c\/li\u003e\n  \u003cli\u003eCompact dimensions: 4.125 inches wide, 1.75 inches high, 0.75 inches thick\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.97 pounds for easy handling and installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement soft jaw for 4-inch bench vises.

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.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJaw Width\u003c\/strong\u003e: 4.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJaw Height\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJaw Thickness\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJaw Shape\u003c\/strong\u003e: Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHard\/Soft\u003c\/strong\u003e: Soft\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJaw Movement Type\u003c\/strong\u003e: Fixed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVise Compatibility\u003c\/strong\u003e: 4 inch Vises\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.97 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GIBRALTAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 428-1063\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51694704820530,"sku":"428-1063","price":48.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0d3400ad93c34cabd52d3012d890eb3f.jpg?v=1788327480","url":"https:\/\/voomisupply.com\/products\/gibraltar-428-1063-soft-vise-jaw-4-125in-flat-aluminum","provider":"Voomi Supply","version":"1.0","type":"link"}
