Gibraltar SID-942-G Gooseneck Clamp Forged Steel 8 in Oal

Product Description

The GIBRALTAR SID-942-G is a forged steel gooseneck clamp rated to ASTM A521 Class CA, designed for secure workholding and clamping applications in industrial and trade settings. Measuring 8 inches overall length, 2-1/8 inches overall width, and 2-1/16 inches overall height, this clamp delivers a rigid, repeatable hold in machining, fabrication, and fixture setups. The neck length of 1-1/4 inches and a slot measuring 2-7/16 inches long by 13/16 inches wide allow for flexible positioning on T-slotted tables and fixture plates. At 4.25 pounds, the clamp is built for durability in demanding shop environments.

This gooseneck clamp is suited for use on milling machine tables, surface plates, jig plates, and similar T-slot workholding surfaces. The not-drilled-or-tapped configuration keeps the strap versatile for a wide range of fixture arrangements. Machinists, tool and die makers, and precision fabricators commonly specify this style of clamp for production setups requiring consistent clamping force and reliable part registration.

Key Features

• Forged steel construction meets ASTM A521 Class CA for strength and consistency
• 8 inches overall length accommodates a wide range of workholding reach requirements
• Slot dimensions of 2-7/16 inches length by 13/16 inches width allow T-bolt compatibility and adjustable positioning
• 1-1/4 inches neck length provides clearance for low-profile clamping setups
• Not drilled or tapped, preserving flexibility for varied fixture configurations
• 4.25 pound forged body resists deflection under clamping loads

Compatibility

Designed as a standard gooseneck strap clamp for use with T-slotted machine tables, fixture plates, and workholding systems accepting a 13/16 inch stud size.

Installation Notes

Installation is typically performed by machinists or tool and die professionals. Ensure the machine table or fixture plate is de-energized and stationary before positioning the clamp. Use the appropriate T-bolt and nut matched to the 13/16 inch slot width and verify that clamping force is applied evenly to prevent workpiece movement. Follow applicable shop safety procedures and fixture design standards for the specific machining operation.
