Gibraltar GS100C Sliding Arm Bar Clamp 4-3/4 in Throat

Product Description

The GIBRALTAR GS100C is a heavy-duty sliding arm bar clamp built for demanding fabrication, assembly, and metalworking applications. It delivers 2,650 lb of clamping pressure through an alloy steel spindle and T-handle drive mechanism, giving trades professionals reliable holding force on a wide range of workpieces. The forged steel frame and pad are finished in nickel for corrosion resistance. The sliding arm design allows quick jaw positioning before final tightening, reducing setup time on the shop floor or job site. At 5.15 pounds, the GS100C is a substantial tool suited for professional-grade clamping tasks.

The GS100C is designed for use in metal fabrication shops, welding operations, woodworking facilities, and general manufacturing environments. It fits into the Series GS product line, which is built around a 30 mm x 15 mm rail profile. The 4-3/4 inch throat depth accommodates a wide range of material thicknesses and part geometries, making it a versatile choice for technicians and tradespeople who need consistent, repeatable clamping force across varied workpiece sizes.

Installation Notes

Bar clamps of this type are typically handled by fabricators, machinists, and general tradespeople without specialized licensing requirements. Inspect the spindle threads and sliding arm mechanism before use to confirm smooth operation and no visible damage. Do not exceed the rated 2,650 lb clamping pressure, and ensure workpieces are fully seated against the pads before applying final load. Store horizontally or racked to prevent rail deflection over time.
