12 in Bar Clamp for Industrial Use
The Bessey Tools MMS-12 is a 12 in bar clamp built for industrial applications. It provides a clamping force of 400 lb and a throat depth of 2 1/4 in. The steel bar and sliding T-handle allow controlled pressure on workpieces. Suitable for woodworking, metal fabrication and general assembly tasks.
Upgrade from Light-Duty Clamps
This clamp replaces lighter models when higher force and deeper reach are required. The 400 lb capacity handles dense hardwoods and steel joints that smaller clamps cannot secure. The jump is worth it when glue-ups demand consistent pressure across wide panels. It is not for buyers who need longer reach or multiple clamps for simultaneous setups.
Capacity and Headroom
The 12 in clamping capacity accommodates standard cabinet frames and furniture components. The 2 1/4 in throat depth clears moderate overhangs and edge profiles. The high-carbon spindle resists wear under repeated tightening cycles. It runs out when projects exceed the 12 in span or require deeper throat clearance for complex assemblies.

Questions about this item
How much clearance does the 2 1/4 in throat depth give behind the jaw?
The throat depth measures 2 1/4 in, so the clamp can reach that far from the bar edge to grip a workpiece.
What is the correct way to engage the sliding T-handle so the 400 lb clamping force is reached?
Slide the jaw along the 1/4 in thick bar until it contacts the work, then turn the T-handle clockwise until the spindle is tight; do not hammer the handle.
When should the spatter-resistant spindle be cleaned or lubricated?
Wipe the high-carbon spindle after welding jobs and apply a light oil if the threads feel gritty; the spatter-resistant finish reduces buildup but does not eliminate maintenance.
