Gibraltar GS30C Sliding Arm Bar Clamp 5.5 in 2650 Lb

Product Description

The GIBRALTAR GS30C is a heavy-duty sliding arm bar clamp built for demanding clamping applications in fabrication, welding, and metalworking environments. Featuring a 5.5-inch throat depth and a maximum clamping pressure of 2,650 pounds, this clamp is engineered to hold workpieces securely during assembly, welding, or machining operations. The forged steel frame and forged steel pad material deliver the structural integrity required for high-load use, while the alloy steel spindle resists wear under repeated torque cycles. A nickel finish provides corrosion resistance for shop environments. The T-Handle design allows fast, controlled tightening without additional tools.

The GS30C is suited for metalworking shops, welding fabrication, and general industrial assembly where a reliable, high-pressure bar clamp is needed. Its 30 mm x 15 mm rail size provides stable sliding action along the bar, making it practical for positioning across a range of workpiece widths. Machinists, welders, and industrial tradespeople typically reach for this clamp when clamping pressure and throat clearance both matter. It ships as a single unit and is ready to put to work out of the box.

Key Features

• 5.5-inch throat depth for clearance on larger workpieces
• 2,650 lb maximum clamping pressure for high-load applications
• Forged steel frame and pad for exceptional structural rigidity
• Alloy steel spindle resists wear under repeated heavy use
• Nickel finish for corrosion resistance in shop environments
• T-Handle design enables fast, controlled tightening by hand

Compatibility

Designed as an OEM-style replacement or direct addition for Series GS sliding arm bar clamp applications requiring a 30 mm x 15 mm rail size and 5.5-inch throat depth.

Installation Notes

No power source is required for installation or operation. Inspect the rail and spindle for damage before each use and ensure the clamping pads are properly seated against the workpiece before applying load. Do not exceed the rated 2,650 lb clamping pressure to avoid deformation of the frame or workpiece. Store in a dry environment to preserve the nickel finish and prevent corrosion.
