Channellock’s No. 444 air brake tool is a 12-inch tongue-and-groove plier with seven channel adjustments designed to quickly and accurately check the clearance between the drum and brake shoe on S-cam brake systems using manual or automatic slack adjusters. The No. 444 is forged from high-carbon steel and offers the PermaLock fastener, engineered to ensure smooth, clean adjustment and eliminating field failure common to traditional nut-and-bolt assemblies.
