Bessey RSC-12 Sliding Arm Bar Clamp 12 in 1100 Lb

Product Description

The BESSEY RSC-12 is a sliding arm bar clamp built for heavy-duty fastening and assembly work in fabrication shops, construction sites, and industrial settings. It delivers up to 1,100 pounds of clamping pressure through a forged steel T-handle and a high carbon steel spindle measuring 0.7 inches in diameter. The rail measures 63/64 inch by 15/32 inch and runs 12 inches in length, giving users a maximum capacity of 12 inches with a throat depth of 5.5 inches. An electrogalvanized finish protects against corrosion in demanding environments. The standard steel pad spreads clamping force evenly across the workpiece, reducing marring and localized stress on the material being held.

The RSC-12 is suited for metal fabrication, carpentry, pipe fitting, and general assembly tasks where a reliable, high-pressure clamp is required. The sliding arm design allows rapid jaw adjustment along the full length of the 12-inch rail before locking down with the spindle, making it efficient for repeated setups. It fits into the RSC series lineup and is appropriate for both professional tradespeople and experienced shop users working with steel, wood, or composite materials.

Key Features

• 1,100 lb clamping pressure for demanding hold applications
• 12-inch maximum capacity with a 5.5-inch throat depth
• Forged steel T-handle for consistent torque application
• High carbon steel spindle, 0.7 inches in diameter, for durability under load
• Electrogalvanized finish for corrosion resistance
• Standard steel pad included for broad contact clamping

Compatibility

Designed as a replacement or additional clamp within the BESSEY RSC series, suitable for standard bar clamp applications requiring a 12-inch rail and 5.5-inch throat depth.

Installation Notes

Position the sliding arm to the approximate jaw opening before engaging the spindle to reduce setup time. Always verify the workpiece is fully seated against the pad before applying full clamping pressure. Do not exceed the rated clamping pressure, as overloading can damage the rail or workpiece. No power tools or special fasteners are required for normal clamp operation.
