Score: 78/100Rankings

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.

The Channellock 3017 is an 8-inch long nose plier designed for precision gripping in confined spaces with a narrow nose and crosshatch teeth. Its primary limitation is the lack of integrated wire cutters, requiring users to carry a separate cutting tool. It is ideal for professionals valuing USA-made durability for precision work in electrical or jewelry applications.

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.




Search results lack specific professional reviews or editor quotes. Manufacturer and retailer descriptions emphasize precision for tight spaces, superior grip/teeth pattern, and rust-proof durability as standout traits. Bulk/reseller specs reinforce high carbon steel strength without cutter functionality.
No consumer reviews or feedback provided in search results. Common themes cannot be identified; reseller pages note general suitability for demanding tasks via crosshatching jaws.
