Constructed from thermoplastic elastomer, it provides a firm, ergonomic grip without the brittleness of standard hard plastics. The knob measures 2.25 inches in head diameter with a 1-inch hub diameter and an overall height of 1 inch. A 1\/4-20 threaded hole with a 0.5-inch thread depth allows for direct installation onto standard fastener stems. Electricians, HVAC technicians, equipment assemblers, and maintenance professionals commonly install this type of knob on panels, enclosures, and adjustment mechanisms.\u003c\/p\u003e\u003cp\u003eThis lobed knob suits residential and light commercial equipment installations where hand-tightened fastening is required. Typical applications include HVAC access panel latches, electrical enclosure hardware, equipment guards, and industrial machinery adjustment points. The 4-lobe profile distributes hand force evenly, allowing secure tightening without tools in moderate-torque applications. Its black thermoplastic elastomer construction resists common shop chemicals and moderate temperature exposure, making it appropriate for use in mechanical rooms, equipment bays, and service panels.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-point lobed profile enables tool-free hand tightening and loosening\u003c\/li\u003e\n\u003cli\u003eThermoplastic elastomer construction provides a durable, grip-friendly surface\u003c\/li\u003e\n\u003cli\u003e2.25-inch head diameter for comfortable hand actuation\u003c\/li\u003e\n\u003cli\u003e1\/4-20 threaded hole with 0.5-inch thread depth fits standard fastener stems\u003c\/li\u003e\n\u003cli\u003e1-inch overall height and 1-inch hub diameter for compact fitment\u003c\/li\u003e\n\u003cli\u003eBlack finish for consistent appearance on panels and enclosures\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-thread replacement or new-installation lobed knob for equipment and enclosures using 1\/4-20 fastener stems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires no special tools — the knob threads directly onto a 1\/4-20 stem by hand. Confirm the mating stem thread is clean and undamaged before installation. Shut down and de-energize any equipment before servicing panels or enclosures where this knob will be installed. Do not exceed the hand-tightening torque appropriate for thermoplastic hardware, as overtightening can crack or strip the hub.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eKnob Type\u003c\/strong\u003e: Lobed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Points\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKnob Material\u003c\/strong\u003e: Thermoplastic Elastomer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31162801\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: G10-2837\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51717382504754,"sku":"G10-2837","price":38.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/92ff3493b45c404ad59c4e163474b6ec.jpg?v=1788539497","url":"https:\/\/voomisupply.com\/products\/gibraltar-g10-2837-lobed-knob-4-point-2-25-in-black","provider":"Voomi Supply","version":"1.0","type":"link"}
