Product Description

Versatile, strong, and durable (view larger).

The Channellock 12-inch Straight Jaw Tongue and Groove Plier (model 440) is the tool every home and garage needs. This plier is built to last with a PermaLock fastener to eliminate nut and bolt failure, patented reinforcing edge to minimize stress breakage and right angle, laser heat-treated teeth to provide a better, longer lasting grip. It's versatile, strong, and durable enough to pass down to your kids.

Channellock uses high carbon C1080 steel for superior performance on the job, and an electronic coating for ultimate rust prevention. The straight jaws provide maximum versatility for a number of different applications, and the unique undercut channels provide a stronger more secure grip, that won't slip on the job. It's completed by Channellock's iconic blue handle, which is both comfortable in your hand and easy to spot in your tool bag.
