Bessey WSM-9 Angle Corner Clamp 7 in 90 Degree Cast Iron

Product Description

The BESSEY WSM-9 is a fixed-angle corner clamp designed to hold workpieces at a precise 90-degree angle across two axes simultaneously. Built with a cast iron jaw and a copper spindle, it delivers rigid, repeatable clamping for woodworking, metalworking, and fabrication tasks. The jaw stands 1.375 inches tall with a 3.5-inch throat depth, and the clamp handles stock up to 7 inches maximum capacity. Automatic adjustment allows the jaws to seat against the workpiece quickly without manual repositioning, saving time on repetitive corner assemblies. Tradespeople and fabricators who need a reliable, no-slip 90-degree reference point during glue-ups, welding tack setups, or frame assembly rely on this style of clamp.

The WSM-9 is suited for both residential shop work and light commercial fabrication environments. It performs well when assembling picture frames, cabinet face frames, metal angle iron, or any application requiring a true right-angle joint. The fixed 90-degree clamping angle eliminates the need to verify squareness with a separate square during setup. It is appropriate for use by carpenters, millworkers, welders, and general fabricators who need consistent corner geometry across multiple workpieces.

Key Features

• Fixed 90-degree clamping angle on 2 axes for consistent, repeatable right-angle joints
• Cast iron jaw construction provides rigid clamping force and long service life
• Copper spindle resists galling and ensures smooth thread engagement under load
• Automatic jaw adjustment seats against workpieces quickly without manual setup
• 3.5-inch throat depth accommodates thicker stock and built-up assemblies
• 7-inch maximum capacity handles a wide range of frame and corner applications

Compatibility

Designed as an OEM-style fixed-angle corner clamp for general woodworking, metalworking, and fabrication applications requiring a precise 90-degree joint.

Installation Notes

Clamp installation and use requires no special licensing, but proper workholding technique is important for safe operation. Before applying clamping pressure, confirm the workpiece is fully seated against both jaw faces to avoid slippage or misalignment. Do not exceed the rated maximum capacity of 7 inches, as overloading cast iron jaws can cause cracking. Release clamping pressure fully before repositioning the clamp on a workpiece.
