Fireball Tool Mantis Grip Pliers – Locking Welding & Fabrication Pliers

The Fireball Tool Mantis Grip Pliers rethink the traditional locking plier with an offset design built specifically for welding, fabrication, fit-up, and metalworking.

Instead of using two similarly sized arms like conventional locking pliers, the Mantis Grip uses one large arm and one compact arm. This unique geometry gives you more flexibility when clamping around tubing, plate, fixtures, and fabricated assemblies—especially when standard locking pliers simply get in the way.

Whether you're fitting up a frame, holding parts for tack welding, or working around an awkward joint, the Mantis Grip is designed to give fabricators better access while maintaining a strong, secure hold.

A Better Locking Plier for Fabrication

Traditional locking pliers work great—until the shape of the project gets in the way.

The large offset arm on the Mantis Grip allows the pliers to step over material, helping you reach clamping points that can be difficult or impossible to access with conventional pliers.

On the opposite side, the compact arm fits into tighter spaces where a full-size clamp arm would interfere with the workpiece.

Simply changing the orientation of the pliers can also create a low-profile clamping setup, keeping more of the tool out of your work area and giving you better access for welding, grinding, measuring, and fit-up.

Built for Welding & Fit-Up

The Mantis Grip is especially useful when working with:

• Square and rectangular tubing

• Plate and flat bar

• Frames and fabricated assemblies

• Welding tables and fixtures

• Sheet metal

• Tack welding and fit-up

• Tight or obstructed clamping locations

The offset design makes these pliers a versatile addition to any welding table, fabrication shop, service truck, or home workshop.

Customizable Threaded Clamping End

Fireball Tool adds even more versatility with a threaded clamping end.

The included threaded bolt can serve as the clamping contact surface, or the threaded connection can be used as a starting point for creating custom jaws, pads, fixtures, or application-specific attachments.

For fabricators who regularly build custom tooling and fixtures, this opens up plenty of possibilities beyond what you'd get from a conventional pair of locking pliers.

Available in 8" and 11" Sizes

8" Mantis Grip

• Overall Length: 8"

• Clamp Capacity: 2.5"

• Throat Depth: 3"

• Step-Over Height: 2.75"

Why Mantis Grip Pliers?

A good fabrication clamp shouldn't dictate how you position your work.

The Fireball Tool Mantis Grip Pliers give welders and fabricators more options for getting around material, reaching tight spaces, and keeping bulky clamp arms away from the weld joint.

They're simple, versatile, and designed around the types of clamping problems fabricators run into every day.

Clamp around it. Reach into it. Stay out of the way. Get the fit-up done.
