JointMaster Adjustable Angle Clamping Pliers

Hold two workpieces securely at almost any angle for fitting, tack welding, and fabrication.
SHT-PA114 JointMaster combines two independent locking pliers on an adjustable pivoting bracket, allowing you to clamp two separate workpieces and position them anywhere from 30° to 275°.

The design works with flat stock, square tubing, and round pipe, making it a flexible solution for frames, joints, brackets, tubing assemblies, and other angled fabrication work. Once the pieces are positioned, the JointMaster helps keep the joint stable so you can focus on fitting and welding.

Why Choose the SHT-PA114 JointMaster?

• 30° to 275° Angle Range: Set acute, right, obtuse, or reflex joint angles.
• Dual Locking Pliers: Two independent pliers hold each workpiece securely.
• 11" Pliers: Longer plier body provides added reach for larger workpieces.
• 3.5" Throat Depth: Provides additional reach around tubing, plate, and fabricated components.
• 3" Clamping Capacity: Accommodates a wide range of material sizes and shapes.
• Mix & Match Materials: Clamp flat plate, square tube, and round pipe in the same setup.
• Clip-On V-Pads: Helps improve grip when clamping round material.
• Strong Holding Pressure: Provides up to 160 lb of holding pressure.
• Heat-Treated Alloy Steel: Built for demanding welding and fabrication environments.
• Nickel-Chrome Finish: Helps resist rust and welding spatter.

Clamp Almost Any Joint Angle

The SHT-PA114 gives you a much wider adjustment range than a fixed 90° clamp. The center pivot allows the two locking pliers to be positioned from 30° through 275°, making it useful for both common and unusual joint configurations.

After positioning the workpieces, lock the angle in place and secure each piece independently with the locking pliers. This makes setup easier when fabricating assemblies that require repeatable or non-standard angles.

Works with Different Material Shapes

Because each side uses its own locking plier, the SHT-PA114 can hold workpieces with different shapes or thicknesses at the same time.

• Square tubing to square tubing
• Round pipe to round pipe
• Round pipe to square tubing
• Flat plate to tubing
• Different material thicknesses in the same joint

This flexibility makes the JointMaster useful for custom fabrication where the two pieces being joined are not always identical.

Clip-On V-Pads for Round Material

The SHT-PA114 uses clip-on V-pads at the top clamping points to improve contact on round pipe and tubing. The V-shaped contact helps keep cylindrical workpieces positioned more securely during fitting and tack welding.
