Bessey 1800-S8 Sliding Arm Bar Clamp 8 in 4-3/4 in Throat

Product Description

The BESSEY 1800-S8 is a heavy-duty F-style sliding arm bar clamp built for professional fabrication, woodworking, and metalworking applications. It delivers up to 1,980 pounds of clamping pressure through a 0.7-inch diameter high carbon steel spindle, giving trades workers a firm, repeatable hold across a wide range of workpieces. The 8-inch maximum capacity and 4-3/4-inch throat depth accommodate both shallow and moderately deep clamping setups. The electrogalvanized steel frame resists corrosion in shop environments. The composite T-handle provides a controlled grip during tightening without requiring separate tools.

The 1800-S8 is suited for residential and commercial shop use, on-site framing and millwork tasks, and bench assembly operations. The sliding arm design allows rapid jaw positioning before final clamping, reducing setup time when working with multiple pieces. The patented 1-3/32 inch by 7/16 inch rail profile adds torsional stiffness to the bar, helping maintain alignment under load. This clamp is appropriate for use by carpenters, ironworkers, fabricators, and general contractors requiring a reliable, mid-capacity bar clamp on the job.

Key Features

• 1,980 pounds of clamping pressure for demanding hold requirements
• Patented rail profile (1-3/32 inches by 7/16 inches) resists twist and flex under load
• 0.7-inch high carbon steel spindle for durability and precise pressure application
• Electrogalvanized steel frame and steel MorPad for corrosion resistance
• Ergonomic BESSEY composite T-handle grip for controlled tightening
• Sliding arm allows fast jaw positioning across the full 8-inch capacity range

Compatibility

Designed as an OEM-style replacement or direct addition within the BESSEY 1800-S Series. Compatible with standard F-style bar clamp applications requiring up to 8 inches of capacity and up to 4-3/4 inches of throat depth.

Installation Notes

No power source or wiring is required for this mechanical clamp. Before applying clamping pressure, confirm workpiece surfaces are clean and free of debris to prevent marring or slippage under load. Use appropriate personal protective equipment when working with high-clamping-force tools, particularly in metal fabrication environments. Inspect the spindle threads and sliding arm mechanism for wear or damage before each use.
