Overview
A graded series of adjustment slots is the working part of this big groove joint plier, which lets the jaws open to a wide range of sizes. Steel handles carry the Channellock blue grip, and the jaws are straight and made from high carbon steel.
A wide capacity and a strong build make it useful for pipe and large nuts. The size fields disagree, with the item type naming a long plier while the length entry is much shorter.
Who it's for
Plumbing fittings, large nuts and pipe work benefit from the leverage of a long groove joint plier. Cramped spaces and small hardware call for a short plier instead.
Pros and cons
- Wide jaw capacity
- High carbon steel jaws
- Channellock blue grip
- Straight jaw pattern
- Size fields disagree
- Too long for tight spaces
- Teeth treatment not described
- Colors listed as black, blue and silver
Performance notes
Wide adjustment slots let the jaws stay parallel across a large range of openings, and the handle length gives leverage on stubborn fittings. High carbon steel supports the teeth under load. The weight makes it steady but tiring on long jobs.
