It features a 1.75-inch head diameter and a 1\/4-20 threaded stem with a 0.5-inch thread length, making it a compact, hand-operable fastening component used across HVAC equipment panels, electrical enclosures, control cabinets, and general industrial assemblies. The TPE construction provides a firm, comfortable grip without requiring tools for installation or removal. Technicians and assemblers in HVAC, electrical, and mechanical trades use this style of knob wherever frequent manual access to a panel or component is required.\u003c\/p\u003e\u003cp\u003eThis lobed knob is suited for light-duty fastening applications in both residential and commercial settings. Typical installations include equipment access panels, control board covers, junction box lids, and service doors on HVAC units, electrical enclosures, and mechanical equipment. The 4-point lobe design improves grip torque over standard round knobs, making it practical in environments where gloves may be worn or access is limited. Its compact overall height of 0.75 inches keeps the profile low on shallow panel surfaces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-point lobed profile for improved manual grip torque\u003c\/li\u003e\n\u003cli\u003eThermoplastic elastomer (TPE) construction for durability and comfortable hand feel\u003c\/li\u003e\n\u003cli\u003e1\/4-20 threaded stem for standard compatibility with common fastener patterns\u003c\/li\u003e\n\u003cli\u003e0.5-inch thread length suitable for thin panel and bracket installations\u003c\/li\u003e\n\u003cli\u003eCompact 0.75-inch overall height for low-profile mounting surfaces\u003c\/li\u003e\n\u003cli\u003eBlack finish for clean appearance on equipment panels and enclosures\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/4-20 threaded lobed knob for use in HVAC, electrical, and general mechanical assemblies requiring manual panel fastening.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by hand without tools, threading the knob onto a 1\/4-20 stud or insert until snug. Ensure the mating thread depth does not exceed the 0.5-inch thread length to avoid bottoming out. Power down or de-energize any equipment before removing or installing panel fasteners on electrical or HVAC enclosures. Do not over-torque by hand, as TPE knobs are designed for tool-free service access.\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 (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: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 0.68 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Height\u003c\/strong\u003e: 0.12 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: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\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: GIBRALTAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5A02B921A8Z003G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51721831252274,"sku":"5A02B921A8Z003G","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6a01eea1071a936c6679500266e24a8e.jpg?v=1788581645","url":"https:\/\/voomisupply.com\/products\/gibraltar-5a02b921a8z003g-lobed-knob-4-point-tpe-black","provider":"Voomi Supply","version":"1.0","type":"link"}
