Crescent Z2 K9 RTZ216 16 Inch Straight Jaw Tongue and Groove Pliers

The Crescent Z2 K9 RTZ216 16-Inch Straight Jaw Tongue and Groove Pliers operate as an adjustable plumbing hand tool engineered to clamp large pipe couplings, drainage rings, and machinery fasteners. Forged from high-strength alloy steel with a polished anti-rust finish, these 3.10-pound pliers feature a 4.2-inch maximum jaw capacity, a 10-position interlocking channel matrix, K9 jaw geometry, and easy-clean dipped handle grips. Designed to deliver a non-slip grip at up to a 35-degree angle with 40% slimmer jaw clearance, this 16-inch tool provides high-torque turning capability across commercial plumbing, municipal water treatment, and industrial maintenance applications.

Best Used For:

• Commercial Water Mains & Large Conduit: Turning large 4-inch drainage rings, pipe couplings, and industrial electrical conduits in tight utility vaults.
• Municipal Water Treatment & Pump Servicing: Adjusting heavy pump valves, flanged fittings, and large pipe unions at angled work positions.

Technical Specifications

Pro-Tip: When using the 16-inch Crescent RTZ216 on large 4-inch pipe couplings, adjust the interlocking channel so the upper and lower handles remain relatively parallel when the K9 jaws engage the fitting. Keeping the handles close together maximizes hand squeezing leverage and prevents palm pinching during high-torque pulls.
