With a head diameter of approximately 3 inches (76.2 mm) and an overall height of 1.25 inches (31.8 mm), this knob provides a secure, hand-tightened grip without the need for tools. The hub diameter measures 1.26 inches (32 mm) and the hub height is 0.63 inches (15.9 mm). It is well-suited for applications where frequent manual adjustment is required and where lightweight, corrosion-resistant hardware is preferred.\u003c\/p\u003e\n\u003cp\u003eThis lobed knob is used across a broad range of commercial and industrial applications including HVAC equipment panels, electrical enclosures, pump assemblies, and mechanical equipment requiring frequent manual operation. The 4-lobe profile allows for confident hand grip and torque transfer without tooling. It is appropriate for both indoor and light-duty outdoor installations where aluminum hardware meets material and corrosion requirements. Machinists, equipment assemblers, maintenance technicians, and field service professionals typically install this type of hardware during equipment assembly or servicing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-point lobed profile for secure hand grip and tool-free adjustment\u003c\/li\u003e\n  \u003cli\u003eMachined from 6063-T5 aluminum for lightweight, corrosion-resistant performance\u003c\/li\u003e\n  \u003cli\u003eHead diameter of 3 inches (76.2 mm) for a comfortable, high-torque grip surface\u003c\/li\u003e\n  \u003cli\u003eHub diameter of 1.26 inches (32 mm) and hub height of 0.63 inches (15.9 mm) for standard mounting fitment\u003c\/li\u003e\n  \u003cli\u003eCompact overall height of 1.25 inches (31.8 mm) for use in space-constrained panel applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install lobed knob for machinery panels, enclosures, and equipment assemblies requiring a 4-point aluminum hand knob with a 76.2 mm head diameter.\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 shaft or threaded insert is clean and free of debris before seating the knob. Verify hub bore and thread specifications are compatible with the receiving shaft before installation. Do not over-torque during installation, as aluminum hardware can be damaged by excessive force.\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: 3 inches (76.2 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 1.26 inches (32 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Height\u003c\/strong\u003e: 0.63 inches (15.9 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 1.25 inches (31.8 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKnob Material\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: 0.21 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-28M-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51722791551282,"sku":"ALH-28M-G","price":21.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/23f8e035d57cd1c6c503f23024914e24.jpg?v=1788595974","url":"https:\/\/voomisupply.com\/products\/gibraltar-alh-28m-g-lobed-knob-4-point-aluminum","provider":"Voomi Supply","version":"1.0","type":"link"}
