It is designed for use in control panels, enclosures, and industrial equipment where a secure, hand-operated grip point is required. The knob features a 1.5-inch projection and a 2-inch center-to-center measurement, with an 8-32 thread size for straightforward fastener compatibility. Electricians, panel builders, and instrumentation technicians commonly specify this type of hardware during enclosure assembly and field retrofits.\u003c\/p\u003e\u003cp\u003eThis round knob handle is suited for light industrial, commercial, and OEM equipment applications. It is commonly installed on control cabinets, HVAC control panels, electrical enclosures, and machine access doors where a smooth, corrosion-resistant grip surface is needed. The nickel-plated brass construction provides durability in dry and lightly humid indoor environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRound knob profile for comfortable hand operation without tools\u003c\/li\u003e\n\u003cli\u003eBrass base material with nickel plating for corrosion resistance\u003c\/li\u003e\n\u003cli\u003e1.5-inch projection suitable for panel-face and door-edge mounting\u003c\/li\u003e\n\u003cli\u003e8-32 thread size compatible with standard machine screw fasteners\u003c\/li\u003e\n\u003cli\u003eSeries A designation for consistent hardware family sourcing\u003c\/li\u003e\n\u003cli\u003eUNSPSC Code 31162801 for procurement and cataloging compliance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose round knob handle for control panels, electrical enclosures, and industrial equipment requiring an 8-32 threaded mount.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by electricians or panel builders during enclosure assembly or service. Power down all circuits to the enclosure before disassembling any panel hardware. Use the appropriate 8-32 fastener and verify thread engagement depth to avoid stripping the brass knob insert. Follow applicable NEC guidelines when working inside energized enclosure environments.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eKnob Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKnob Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Nickel Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Center\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31162801\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ELECTRO HARDWARE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A3531-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELECTRO HARDWARE","offers":[{"title":"Default Title","offer_id":51728858415410,"sku":"A3531-7","price":23.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/67a601039cb9babf820c3347eca98510_46275129-ad45-4de3-acf3-d84bde75d1df.jpg?v=1788696983","url":"https:\/\/voomisupply.com\/products\/electro-hardware-a3531-7-round-knob-handle-nickel-plated","provider":"Voomi Supply","version":"1.0","type":"link"}
