Channellock 432
Score: 88/100Rankings

The Channellock 432 is a robust 10-inch V-Jaw Tongue & Groove Plier designed for gripping round stock and tubing with increased contact points. It features a unique V-jaw and PERMALOCK fastener for durability, though it lacks the quick-adjust mechanism of the 432X model. Best suited for plumbers and mechanics handling cylindrical objects where traditional jaws slip.

The Channellock GL12 is a 12.5-inch GRIPLOCK Tongue and Groove Plier designed for electricians and plumbers to grip irregular shapes and 1/2-inch electrical fittings. It features a laser-hardened jaw, PERMALOCK fastener, and an ergonomic offset head for enhanced leverage and durability. It is ideal for tightening conduit locknuts, gripping round tubing, and maintenance on fittings where standard pliers slip.

Manufacturer and retailer specs emphasize the GL12's ergonomic offset head for more leverage and versatile jaw for many shapes, calling it built to last with PERMALOCK eliminating nut/bolt issues. One expert notes it is one of their favorite tools for perfectly sizing 1/2-inch electrical fittings and lockrings.
Common praise includes a strong, reliable grip on fittings and lockrings that lasts years without slipping, along with comfort for extended use. Recurring complaints note limited direct user feedback in results, with some users noting the weight feels bulky for precision tasks.
