Built to ASTM A521 Class CA specifications, this clamp features an 11\/16-inch stud size and 11\/16-inch travel, giving installers reliable adjustability within the slot. The overall length is 4 inches, with an overall width of 1-5\/8 inches and an overall height of 3\/4 inches. The slot measures 1-3\/8 inches long by 11\/16 inches wide. Forged steel construction provides durability and load-bearing integrity suited to demanding mechanical and structural fastening tasks. This part is sold individually and ships as a single unit.\u003c\/p\u003e\u003cp\u003eThe SID-901-G heel clamp is used in mechanical and structural fastening applications where a non-drilled, non-tapped strap-style clamp is required. Common install scenarios include securing equipment bases, machinery mounts, and structural members where slot adjustment is needed for alignment. The heel clamp profile makes it well suited for applications requiring a low-profile, rigid clamping point. It is typically installed by millwrights, pipefitters, or mechanical contractors working on equipment mounting and alignment projects.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eForged steel construction rated to ASTM A521 Class CA for high-strength fastening\u003c\/li\u003e\n\u003cli\u003e11\/16-inch stud size with 11\/16-inch travel for adjustable positioning\u003c\/li\u003e\n\u003cli\u003eSlot dimensions of 1-3\/8 inches long by 11\/16 inches wide allow precise alignment\u003c\/li\u003e\n\u003cli\u003eHeel clamp strap style — not drilled or tapped, simplifying installation\u003c\/li\u003e\n\u003cli\u003eCompact profile: 4 inches OAL, 1-5\/8 inches wide, 3\/4 inches tall\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style forged steel heel clamp for mechanical and structural fastening applications requiring an 11\/16-inch stud size and ASTM A521 Class CA-rated clamping hardware.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by millwrights, pipefitters, or mechanical contractors. Ensure all equipment is de-energized and load is relieved from the mounting surface before removing or installing clamps. Use properly rated fasteners matching the 11\/16-inch stud specification. Verify alignment within the slot before final torque is applied per applicable project or equipment specifications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStud Size\u003c\/strong\u003e: 11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTravel\u003c\/strong\u003e: 11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 1-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSlot Dimensions\u003c\/strong\u003e: 1-3\/8 inches long x 11\/16 inches wide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Forged Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: ASTM A521 Class CA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrap Style\u003c\/strong\u003e: Heel Clamp — Not Drilled or Tapped\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: SID-901-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51695427780914,"sku":"SID-901-G","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d999ed4aaa35c4d28874f95c4133e4c1.jpg?v=1788334912","url":"https:\/\/voomisupply.com\/products\/gibraltar-sid-901-g-heel-clamp-4in-forged-steel-astm-a521","provider":"Voomi Supply","version":"1.0","type":"link"}
