Interface pads sit between the sander backing plate and the abrasive disc, providing a compliant layer that allows the abrasive to conform to contoured or irregular surfaces. The face and back both use hook and loop attachment, making disc changes fast and secure. This pad is vacuum-compatible, featuring 5 vacuum holes to support dust extraction during sanding operations. It is typically installed by auto body technicians, woodworkers, and finishing trades who need consistent surface contact across non-flat workpieces.\u003c\/p\u003e\n\u003cp\u003eThe 53978 is suited for finishing and material removal applications where surface conformability is critical. The interface layer reduces the risk of swirl marks and uneven stock removal on curved panels, moldings, or composite surfaces. Common applications include automotive body prep, furniture finishing, and general industrial surface conditioning. The vacuum pad design supports connection to shop vac or integrated sander dust collection systems, keeping the work area cleaner and extending abrasive life.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-inch diameter round pad fits standard 5-inch random orbital sanders\u003c\/li\u003e\n  \u003cli\u003eInterface construction adds compliance layer between backer and abrasive for improved surface conformability\u003c\/li\u003e\n  \u003cli\u003eHook and loop face secures abrasive discs quickly without tools\u003c\/li\u003e\n  \u003cli\u003eHook and loop back attaches directly to the sander backing plate\u003c\/li\u003e\n  \u003cli\u003e5 vacuum holes align with dust extraction ports for integrated chip and dust removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style interface backing pad compatible with random orbital sanders that accept a 5-inch hook and loop abrasive disc with a vacuum pad configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePower down and unplug the sander before installing or removing the interface pad. Align the vacuum holes in the interface pad with the corresponding ports on the sander backing plate and the abrasive disc to maintain dust extraction performance. Hook and loop connection does not require tools, but ensure the pad is fully seated before operating the sander. Inspect the pad periodically for wear or delamination and replace when the hook and loop face shows significant degradation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePad Type\u003c\/strong\u003e: Interface\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: Hook and Loop\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\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: 53978\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DYNABRADE","offers":[{"title":"Default Title","offer_id":51542627320114,"sku":"53978","price":34.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5fff0eed33558198bf8f974f24846a43.jpg?v=1785903969","url":"https:\/\/voomisupply.com\/products\/dynabrade-53978-interface-backing-pad-5-inch-hook-loop","provider":"Voomi Supply","version":"1.0","type":"link"}
