Gibraltar G20CS Sliding Arm Bar Clamp 4 Inch Throat

Product Description

The GIBRALTAR G20CS is a sliding arm bar clamp engineered for heavy-duty workholding applications. It delivers 992 pounds of clamping pressure through a T-handle actuated spindle, making it well suited for metalworking, fabrication, and general industrial clamping tasks. The frame and pad are constructed from forged steel for resistance to deformation under load, while the alloy steel spindle maintains thread integrity through repeated use cycles. A nickel finish provides basic corrosion resistance in shop environments. The 19.50 x 9.50 millimeter rail accepts standard sliding arm components and positions this clamp within the Series G product family.

The G20CS is used in metal fabrication shops, machine shops, and general industrial settings where secure, repeatable workholding is required. The 4-inch throat depth accommodates workpieces and fixtures of moderate cross-section thickness. It is appropriate for bench work, jig assembly, and fixturing operations where a bar clamp with significant clamping force is needed. Machinists, fabricators, and toolmakers are the primary installers and users of this clamp type.

Key Features

• 4-inch throat depth accommodates a wide range of workpiece thicknesses
• Forged steel frame and pad for high load resistance and durability
• Alloy steel spindle maintains thread integrity under repeated torque cycles
• T-handle style provides positive grip and controlled force application
• Nickel finish for basic corrosion resistance in shop environments

Compatibility

Designed as an OEM-style replacement or direct-use sliding arm bar clamp within the GIBRALTAR Series G clamp family, compatible with 19.50 x 9.50 mm rails.

Installation Notes

This clamp is installed and used by machinists, fabricators, and toolroom professionals. Ensure the workpiece and clamp surfaces are clean and free of burrs before applying clamping pressure to prevent marring or slippage. Do not exceed the rated 992 lb clamping capacity, as overloading can cause frame deformation or spindle thread failure. Follow applicable shop safety practices when securing workpieces for cutting, welding, or machining operations.
