Gibraltar G30CS Sliding Arm Bar Clamp 5.5 Inch Throat

Product Description

The GIBRALTAR G30CS is a sliding arm bar clamp built for heavy-duty workholding applications. It delivers 1,480 pounds of clamping pressure through an alloy steel spindle and T-handle drive, making it suitable for metalworking, fabrication, and industrial assembly tasks. The frame and pad are both forged steel, finished in nickel for corrosion resistance. With a 5.5-inch throat depth and a 25 mm x 12 mm rail profile, this clamp is sized to reach into moderate-depth workpieces without sacrificing rigidity. Machinists, welders, and fabricators install this clamp where consistent, repeatable clamping force is required on the bench or at a fixture.

The G30CS belongs to Gibraltar's Series G bar clamp line. It is suited for use in metalworking shops, fabrication facilities, and manufacturing environments where a sliding arm design is needed to quickly position and lock the jaw before applying final clamping pressure through the spindle. The T-handle provides controlled torque application without the need for additional tooling. This clamp is appropriate for both production and maintenance environments requiring a forged steel clamping solution.

Key Features

• 1,480 lb clamping pressure for high-force workholding applications
• 5.5-inch throat depth accommodates moderate-depth workpieces
• Forged steel frame and pad for durability under repeated load cycles
• Alloy steel spindle provides reliable thread engagement and long service life
• T-handle drive allows controlled clamping without additional tools
• Nickel finish offers corrosion resistance in shop environments

Compatibility

Designed as an OEM-style replacement or direct-use sliding arm bar clamp suitable for general metalworking and fabrication workholding setups requiring a 25 mm x 12 mm rail profile and 5.5-inch throat depth.

Installation Notes

This clamp is installed by machinists, fabricators, and tooling technicians without specialized trades licensing. Position the sliding arm to the approximate jaw opening before engaging the spindle to apply final clamping pressure. Inspect the spindle thread and pad contact surfaces for wear or damage before each use under high clamping loads. Do not exceed the rated clamping pressure to avoid deformation of the forged components or workpiece damage.
