Gibraltar SID-921-G U-shaped Strap Clamp Forged Steel

Product Description

The GIBRALTAR SID-921-G is a U-shaped strap clamp designed for secure workholding and fixturing applications in machine shops, fabrication facilities, and maintenance environments. Forged from steel for high strength and durability, this clamp measures 2 inches wide, 7/8 inches high, and 6 inches in overall length. The slotted design allows 5.5 inches of travel with a slot length of 5.5 inches and a slot width of 11/16 inches. The stud size is 11/16 inches. Machinists, tool and die makers, and maintenance technicians typically install and use this type of clamp in manual and CNC machining setups.

The SID-921-G is suited for use on milling machines, drill presses, and surface plates where a reliable U-strap clamp is needed to secure workpieces to a table or fixture plate. The slotted opening accommodates T-slot table configurations, allowing adjustment along the length of the slot for flexible workpiece positioning. It is appropriate for both production and job-shop environments requiring a heavy-duty forged steel clamp.

Key Features

• Forged steel construction for high clamping strength and resistance to deformation under load
• U-shaped profile fits standard T-slot fixturing tables and machine beds
• 5.5 inches of travel allows flexible positioning across the slot length
• 11/16 inches stud size and slot width for compatibility with standard T-slot hardware
• 6 inches overall length provides stable clamping leverage
• Compact 2 inches wide by 7/8 inches high profile minimizes interference in tight setups

Compatibility

Designed as an OEM-style replacement or direct-use forged steel strap clamp for standard T-slot workholding systems on milling machines, drill presses, and fixture plates accepting an 11/16 inches stud diameter.

Installation Notes

Installation is typically performed by a machinist or maintenance technician using standard T-slot bolts, studs, and step blocks. Always ensure the machine table or fixture plate is clean and free of chips before seating the clamp. Verify stud and nut engagement is adequate before applying clamping force. Follow applicable shop safety procedures and machine manufacturer guidelines when securing workpieces.
