Built to ASTM A521 standards and rated Class CA, this clamp measures 6 inches overall length, 1-3\/4 inches overall width, and 1-9\/16 inches overall height. The gooseneck profile allows the clamp to step over obstructions and apply clamping force directly to a workpiece surface. Machinists, tool and die makers, and fabrication professionals use this style of clamp on milling machines, drill presses, and fixture plates where a low-profile hold-down solution is required.\u003c\/p\u003e\u003cp\u003eThe SID-941-G is suited for use on manual and CNC machining centers, surface plates, and custom fixturing setups in both job shop and production environments. The slot dimensions of 1-11\/16 inches length by 11\/16 inches width accommodate standard T-slot hardware. A neck length of 1-1\/8 inches provides clearance for stepped workpieces and irregularly shaped parts. This clamp ships individually and is available for single-unit ordering.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eForged steel construction to ASTM A521, Class CA for high strength and durability\u003c\/li\u003e\n\u003cli\u003eGooseneck profile steps over workpiece edges for direct surface clamping\u003c\/li\u003e\n\u003cli\u003eSlot dimensions: 1-11\/16 inches length by 11\/16 inches slot width for standard T-slot hardware\u003c\/li\u003e\n\u003cli\u003eNeck length of 1-1\/8 inches provides clearance for stepped or irregular workpieces\u003c\/li\u003e\n\u003cli\u003eCompact form factor: 6 inches OAL, 1-3\/4 inches wide, 1-9\/16 inches tall\u003c\/li\u003e\n\u003cli\u003eNot drilled or tapped — ready for standard stud-and-strap clamping setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 11\/16 inch stud hardware on standard T-slot milling tables, drill press tables, and modular fixturing systems that accept this slot width.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or toolroom technicians using standard T-slot nuts, studs, and step blocks. Ensure the machine table is powered down and all moving elements are at rest before adjusting or repositioning clamps on the work surface. Use a torque wrench appropriate for the stud size to achieve consistent clamping force without distorting the workpiece. Always verify that the clamp is seated flat and that the stud is centered in the slot before engaging the machine.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 1-9\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSlot Length\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSlot Width\u003c\/strong\u003e: 11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStud Size\u003c\/strong\u003e: 11\/16 inches\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: Gooseneck, Not Drilled or Tapped\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 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: SID-941-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51716012245298,"sku":"SID-941-G","price":29.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2199d210647c342ddc7fe2f1ba06850e.jpg?v=1788520964","url":"https:\/\/voomisupply.com\/products\/gibraltar-sid-941-g-gooseneck-clamp-forged-steel-astm-a521","provider":"Voomi Supply","version":"1.0","type":"link"}
