CHANNELLOCK 428 Plier

CHANNELLOCK 428 Tongue and Groove Pliers are professional-grade 8-inch straight jaw pliers engineered for superior gripping strength, durability, and dependable performance in demanding commercial and industrial environments. Manufactured from forged high-carbon U.S. steel, these pliers are built to withstand years of daily use while delivering the precision and strength professionals expect.

The CHANNELLOCK 428 Tongue and Groove Pliers feature straight jaws with precision-machined, laser-hardened 90-degree teeth that provide a secure grip on flat surfaces, pipe, fittings, fasteners, and a wide variety of materials. The undercut tongue-and-groove design prevents slipping under heavy loads, while the PERMALOCK® fastener eliminates nut and bolt failure for increased joint strength and longer service life.

For mechanical insulation contractors, the CHANNELLOCK 428 Tongue and Groove Pliers are an excellent tool for gripping pipe, tightening and loosening fittings, positioning insulation materials, securing metal jacketing, and performing general HVAC fabrication and installation work. Their compact 8-inch size makes them especially useful in tight mechanical rooms and confined work areas where larger pliers are difficult to maneuver.

The patented SAFE-T-STOP® feature helps reduce the risk of finger pinch by preventing the handles from closing completely during use. Ergonomic CHANNELLOCK BLUE® comfort grips provide a secure, non-slip hold while reducing hand fatigue during repetitive tasks. A rust-resistant coating helps protect the forged steel construction in harsh jobsite conditions.

Whether you’re installing mechanical insulation, servicing HVAC systems, performing plumbing repairs, or handling industrial maintenance, the CHANNELLOCK 428 Tongue and Groove Pliers deliver the gripping power, durability, and reliability professionals depend on every day.
