The Channellock 12 in. Straight Jaw Tongue and Groove Pliers are constructed with high-carbon C1080 steel and fashioned with laser heat-treated teeth that clamp down perpendicularly for strong, nonslip jaw action. Undercut tongue-and-groove fabrication allows this heavy-duty tool to perform without slipping, giving users the confidence to impart maximum torque and leverage aided by the comfort and command of the ubiquitous CHANNELLOCK BLUE grips. The patented PermaLock fastener eliminates bolt and nut failure in any of the seven adjustable jaw settings, supplying utmost strength to loosen and tighten threaded hardware up to 2-1/4 in. in addition to other fastening and crimping tasks.

This is a gripping plier and does not have the ability to cut.

The CHANNELLOCK 440(R) is a tongue and groove plier. It primarily functions as a gripping plier and does not contain a shear or cutting edge like some "slip joint" pliers may have as an additional feature to gripping.

Rated 4.8 out of 5 by 61 reviewers.
Rated 5.0 out of 5.0 by strong pliers Every tool box should have at least one pair of channel locks, at least. The teeth provide a nice bite on anything you plane to grab with them and the handles are a good length to get a lot of torque from as well. Give it a shot of oil at the joint every now and then and you should have this tool for a long time. The best part about these is they are one of the few things still made in America. May 9, 2016
Rated 5.0 out of 5.0 by Gets the job done This is an absolutely essential tool and no one makes a better one than channel lock. In fact, your probably not a real man without a couple of these. April 26, 2016
Rated 5.0 out of 5.0 by Made in the USA! I have quite a few of these tools and they never disappoint. Great materials, quality workmanship, and made in America; can't beat them. You want the best tools for your money? Look no further than ChannelLock! August 18, 2015
Rated 5.0 out of 5.0 by Awesome tool Great product , no slip grip . A tool I can use everyday March 8, 2016
Rated 5.0 out of 5.0 by Real Nice Pliers Never much for tongue and groove pliers because the pliers would slip off the nut and pinch your fingers. Trying the Channel Lock's has changed my way of thinking. Compared the old pliers with the Channel Lock's and there is a difference while not in a big way visually, it is in the engineering. I could go on but it would be easier to read the packaging. Put on a ball unit on my hitch. On the nut end, I used an adjustable wrench and for the ball end the Channel Lock's, firm and steadfast grip. There will be many uses for these pliers in the future. May 27, 2015
Rated 2.0 out of 5.0 by Once were a great product I have been using channellocks for 20+yrs and using them hard every day I would have to buy a couple new 440's about every 3yrs, now I have to buy a couple 440's every year since they made the jaws wider they don't grip like they once did and I seem to bend the jaws very easily something I have only done since they made the jaws wider. I have tried many different 12in tongue and groove pliers they all seem to be poorly made so I just have to keep supporting channellock a little more buy wasting 32 bucks every year on a tool that should last longer February 2, 2016
Rated 5.0 out of 5.0 by Everyone needs a Channellock For the price, you can't beat a good pair of Channellocks. Unless you loose them, you'll have them for life. If used properly (in the right direction of the turn) Channellocks offer a much stronger grip (turn pressure actually increases the grip) than regular pliers. These 12 in Channellocks open to 2.5 inches and offers the most leverage of any of the smaller Channellocks I have, including the 10 in. June 9, 2015
Rated 5.0 out of 5.0 by CHANNELLOCK quality pliers I will admit there are a few brands of tools I am partial to, and CHANNELLOCK is one of them. All of the CHANNELLOCK tools I have owned over the years have held up very well, and I see no reason why these pliers will be any different. Many (probably most) hand tools these days are made in China. "Fiercely made in Meadville, PA" is clearly on the packaging for these tools. Some of the quality features include being made out of high carbon C1080 steel, having an electronic coating for rust prevention, and having laser heat-treated right-angle teeth. The blue "comfort grip" rubber handles cover clear to the ends of the handles, which I like. (On many tools today, the grips stop short of the end of the handle.) In terms of usability, these pliers are a full 12" long, and and it's widest setting the jaws are 2 1/4" when fully "closed". I will mention that on this particular pair of pliers, there were some imperfections on the surface of the back of the pliers. (I included a photo of this.) While I think this was just cosmetic, it did surprise me a little, as I haven't seen this on other CHANNELLOCK pliers I have owned. If I could do half-star ratings, I probably would have knocked the quality rating down to 4.5 stars for this particular pair. But other than the slight cosmetic issue above, I expect I will get many years of good use out of these, and would recommend them to anyone looking for quality tongue-and-groove pliers. July 8, 2015
