Power down and lock out the machine before setting up or adjusting any fixturing hardware. Ensure studs are fully engaged in the T-slot nut and that clamp straps are level or angled slightly toward the workpiece for maximum holding force. Do not overtighten nuts beyond hand-snug plus a controlled torque appropriate for the stud diameter — consult applicable shop standards for proper clamping procedure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSet Piece Count\u003c\/strong\u003e: 52 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClamp Set Type\u003c\/strong\u003e: Step Block and Clamp Set\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStep Block Width\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eT-Slot Size\u003c\/strong\u003e: 7\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStud Thread\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNut Width\u003c\/strong\u003e: 11\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStud Lengths\u003c\/strong\u003e: 3, 4, 5, 6, 7, and 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 18.5 pounds\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: 20412G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51723019223346,"sku":"20412G","price":336.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/66080658c92e7bde01e3fff3ce082cac.jpg?v=1788599368","url":"https:\/\/voomisupply.com\/products\/gibraltar-20412g-52-piece-step-block-clamp-set","provider":"Voomi Supply","version":"1.0","type":"link"}
