Expand-O Pliers

Product Overview

The patented Expand-O Pliers are high-performance, reverse-action locking pliers designed to push materials apart rather than squeezing them together. Forged from heat-treated alloy steels, they feature dual self-adjusting v-pads that instantly mold to flat, round, or angled work geometries without slipping. An integrated bottom magnetic v-pad firmly anchors the weight of the tool vertically or horizontally to steel plates or welding tables, delivering hands-free fixturing so your hands remain free to position, clamp, or weld your workpieces. This versatile specialty tool is an essential addition to any welding shop, mechanical garage, or woodworking studio, delivering 500 to 900 pounds (227 to 408 kg) of spreading force. Whether you are fitting tight brackets, aligning pipe joints, spreading compressed suspension tabs, correcting over-bends, or separating frozen joints, the Expand-O series provides unmatched mechanical precision and acts as your ultimate "third hand" on the job.

Adjustable locking pliers with a screw mechanism for gripping.

Innovative Reverse-Action Spreading

Unlike traditional pliers that squeeze, these jaws move in opposite directions to push against two surfaces and force objects apart.

Immense Spreading Force

Despite its hand-held size, this locking tool delivers a powerful 500 lbs of force on the PE6 model and up to 900 lbs on the PE10 variant.

Vast Fabrication Applications

Extremely useful for fitting brackets, correcting over-bends, inserting panels into U-channels, aligning pipe joints, and separating frozen assemblies.

Industrial Steel Construction

The mechanical body is forged from premium heat-treated Alloy Steel, Carbon Steel, and Chromium-Vanadium Steel to withstand intense workshop abuse.

Compact Spatial Footprint

Designed with a highly compact profile to comfortably fit into tight corners and narrow gaps.

Two Versatile Size Selections

Available in a 6.5-inch compact version (PE6) with a 3/4" stroke, or a larger 10-inch version (PE10) with a 1-3/8" stroke.

Customizable Expansion foot

Equipped with a threaded jaw foot that spins out or in, allowing the operator to adjust the tool's resting width to span various gap distances.

Ergonomic Operator Comfort

Built with an ergonomically shaped handle and slip-resistant plastic grips to ensure user comfort and safety under heavy load pressures.
