12-inch Sliding Arm Bar Clamp
The Bessey 1200-S12 provides a 12-inch clamping capacity with a 1320 lb force rating for industrial holding tasks. Its steel bar measures 7/16 inch thick by 1-1/8 inch wide and features a patented rail profile. A 5-1/2 inch throat depth reaches past obstructions. The tool weighs 4.32 units.
Installation and Common Issues
The sliding arm moves along the bar and locks by hand pressure; no extra tools are required. Swivel pads are replaceable when worn. Misalignment can occur if the spindle is not kept clean or if the bar is bent from overload. Apply force evenly to avoid jaw distortion.
Pre-Purchase Checks
Verify the 12-inch capacity matches your maximum workpiece width. Confirm the 5-1/2 inch throat depth clears your fixture or bench edge. Ensure the 1320 lb force suits the material without crushing it. Check that the 7-3/4 inch overall width fits your available workspace.

Questions about this item
How do I confirm the clamp is holding at its full 1320 lb force after setup?
Tighten the spindle until the sliding arm locks firmly on the rail; the patented rail profile and replaceable swivel pad should grip evenly across the 1 1/2 in jaw pads without slipping.
What comes in the box and what must I buy separately?
The clamp ships complete with the steel bar, sliding arm, steel handle, standard jaw pads and replaceable swivel pad; no extra accessories are required for basic clamping.
Which capacity should I choose — 12 in or a longer reach?
Choose the 12 in clamping capacity when your workpiece fits within that span; the 5 1/2 in throat depth and 7/16 in bar thickness suit general industrial tasks.
