The pad measures 5 inches in diameter and features a hook and loop face on one side with a PSA adhesive back on the other, allowing the installer to switch abrasive attachment styles on compatible tools without replacing the entire sander. It includes 5 vacuum holes to support dust extraction during use. This pad is installed by abrasive finishing professionals, painters, and bodywork technicians working with pneumatic or electric random orbital sanders.\u003c\/p\u003e\n\u003cp\u003eThe 53979 is suited for applications where a single random orbital sander must accept two different abrasive backing styles across jobs. Typical install scenarios include automotive body shops, woodworking shops, and general surface preparation environments where operators stock both PSA and hook and loop abrasive discs and need to switch between them on the same tool. The vacuum hole pattern supports shop vacuum or inline dust collection setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eConverts random orbital sanders between hook and loop and PSA abrasive systems\u003c\/li\u003e\n  \u003cli\u003e5 inch round profile for broad surface coverage\u003c\/li\u003e\n  \u003cli\u003eHook and loop face accepts standard loop-backed abrasive discs\u003c\/li\u003e\n  \u003cli\u003ePSA adhesive back mounts securely to the sander backing plate\u003c\/li\u003e\n  \u003cli\u003e5 vacuum holes for dust extraction compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style conversion backing pad for random orbital sanders that accept a 5 inch round PSA-mount pad interface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by removing the existing backing pad from the random orbital sander and pressing the PSA back of the 53979 firmly onto the sander plate. Ensure the sander is fully powered down and air supply is disconnected before servicing any pad or attachment. Align the vacuum holes with the tool port pattern to maintain dust extraction performance. Do not operate the pad without an abrasive disc mounted to the hook and loop face.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePad Type\u003c\/strong\u003e: Conversion\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePad Diameter\u003c\/strong\u003e: 5 inches (127 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace Type\u003c\/strong\u003e: Hook and Loop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Type\u003c\/strong\u003e: Adhesive\/PSA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVacuum Type\u003c\/strong\u003e: Vacuum Pad\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Vacuum Holes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Tool Type\u003c\/strong\u003e: Random Orbital Sander\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: DYNABRADE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 53979\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DYNABRADE","offers":[{"title":"Default Title","offer_id":51542444540210,"sku":"53979","price":25.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c2c0c258a553127f13aa1a148e090389.jpg?v=1785900729","url":"https:\/\/voomisupply.com\/products\/dynabrade-53979-conversion-backing-pad-5-inch-hook-loop","provider":"Voomi Supply","version":"1.0","type":"link"}
