Built to ASTM A521 Class CA standards, this clamp features a 15\/16 inch stud size and 2-3\/4 inch travel, giving technicians and machinists the clamping range needed for secure fixture setups. At 10 inches overall length and 2-1\/2 inches overall width, it is sized for medium-duty workholding tasks on machine tables, jigs, and fixtures. The slot measures 3-11\/16 inches long by 15\/16 inches wide. This is a non-drilled, non-tapped strap-style clamp supplied as a single unit.\u003c\/p\u003e\u003cp\u003eThe SID-904-G heel clamp is used in manufacturing, maintenance, and fabrication environments where reliable workholding is required. It suits applications on milling machines, drill presses, and similar equipment where a T-slot or bolt-down clamping arrangement is standard. At 7 pounds, the forged steel construction provides the mass and rigidity expected in production shop settings. It is installed by machinists, millwrights, and maintenance technicians in both job shop and production floor environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eASTM A521 Class CA forged steel construction for high strength and durability\u003c\/li\u003e\n\u003cli\u003e15\/16 inch stud size with 2-3\/4 inch travel for versatile clamping range\u003c\/li\u003e\n\u003cli\u003eHeel clamp strap style — not drilled or tapped, ready for standard stud-and-nut setups\u003c\/li\u003e\n\u003cli\u003eSlot dimensions of 3-11\/16 inches long by 15\/16 inches wide for precise positioning\u003c\/li\u003e\n\u003cli\u003e10 inch overall length with 1-3\/8 inch overall height for low-profile clamping\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use heel clamp for standard T-slot workholding setups using 15\/16 inch stud hardware.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or millwrights following standard workholding procedures.
