It is designed for manual fastening and adjustment applications where a tool-free grip is needed. The knob features a 1.52-inch head diameter and accepts a 1\/4-20 threaded stem with a 0.50-inch thread length. TPE construction provides a firm, comfortable grip and resistance to moderate industrial use. This type of knob is commonly installed by HVAC technicians, electricians, plumbers, and equipment maintenance professionals on panels, enclosures, and mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis lobed knob is suited for use on control panels, access covers, equipment enclosures, and light-duty mechanical assemblies across residential and light commercial trade applications. The 5-lobe profile allows finger-tightening without tools, making it practical for service panels and components that require regular access. The 1\/4-20 thread size is a standard fastener size found across a wide range of equipment in HVAC, electrical, and plumbing trades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-point lobed profile allows tool-free finger tightening and loosening\u003c\/li\u003e\n  \u003cli\u003eThermoplastic elastomer construction provides a secure, comfortable grip\u003c\/li\u003e\n  \u003cli\u003e1.52-inch head diameter with a 0.69-inch hub diameter\u003c\/li\u003e\n  \u003cli\u003eStandard 1\/4-20 threaded stem with 0.50-inch thread length\u003c\/li\u003e\n  \u003cli\u003eOverall height of 1.09 inches with a hub height of 0.18 inches\u003c\/li\u003e\n  \u003cli\u003eBlack finish for clean appearance on panels and enclosures\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or new-installation lobed knob for equipment panels, access covers, and mechanical assemblies using 1\/4-20 threaded fastener connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires no special tools — thread the knob onto a 1\/4-20 stud or bolt by hand. Before servicing any panel or enclosure, de-energize electrical circuits and follow applicable lockout\/tagout procedures per OSHA and NEC guidelines. Do not overtighten; TPE knobs are designed for hand-torque applications only. Verify thread engagement is sufficient for the application load before returning equipment to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKnob Material\u003c\/strong\u003e: Thermoplastic Elastomer (TPE)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1.52 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 0.69 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Height\u003c\/strong\u003e: 0.18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 1.09 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.50 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: GIBRALTAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5B40B921A8Z002G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51723126210866,"sku":"5B40B921A8Z002G","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/15a52eaf8d76884fbd0594d479ae9ddb.jpg?v=1788600960","url":"https:\/\/voomisupply.com\/products\/gibraltar-5b40b921a8z002g-lobed-knob-5-point-black","provider":"Voomi Supply","version":"1.0","type":"link"}
