With a 63.5 mm head diameter and a 25 mm hub diameter, this knob provides a firm, ergonomic grip for frequent or tool-free fastening. The 6063-T5 alloy offers a solid balance of strength and corrosion resistance, making it suitable for use in light industrial settings. Technicians and assemblers install this type of hardware on panels, fixtures, jigs, and machinery requiring repeatable manual adjustment.\u003c\/p\u003e\n\u003cp\u003eThis lobed knob is suited for general industrial and mechanical assembly applications where a standard threaded hub knob is needed for hand-operated clamping or positioning. It fits residential and commercial equipment panels, test fixtures, and industrial machinery. The 4-lobe design allows secure grip without tools, making it a practical choice for service panels and adjustable mounting hardware encountered by electricians, equipment installers, and maintenance technicians.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-point lobed profile for ergonomic, tool-free hand tightening\u003c\/li\u003e\n  \u003cli\u003e63.5 mm head diameter for a wide, comfortable grip surface\u003c\/li\u003e\n  \u003cli\u003e6063-T5 aluminum construction balances strength with corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e25 mm hub diameter with 14.3 mm hub height for secure fastener engagement\u003c\/li\u003e\n  \u003cli\u003e28.6 mm overall height suits standard panel and fixture mounting depths\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.14 pounds, reducing added load on assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard lobed knob replacement or new-installation component for industrial panels, mechanical fixtures, and adjustable equipment assemblies requiring a 25 mm hub interface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by maintenance technicians or equipment assemblers using standard hand tools. Ensure the mating threaded stud or insert matches the hub bore specification before installation. Power down or de-energize any associated equipment before servicing panels or assemblies where this knob is being installed or replaced. Do not overtighten beyond hand-tight unless the application specifically requires a tool-assisted final snug.\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: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 63.5 mm (approximately 2.5 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 25 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Height\u003c\/strong\u003e: 14.3 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 28.6 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 6063-T5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31162801\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: ALH-25M-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51695385936178,"sku":"ALH-25M-G","price":16.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fb089f0fbb21718bee38a2031faea0c7.jpg?v=1788334484","url":"https:\/\/voomisupply.com\/products\/gibraltar-alh-25m-g-lobed-knob-4-point-aluminum","provider":"Voomi Supply","version":"1.0","type":"link"}
