The RIDGID 31115 Aluminium Straight Pipe Wrench, in red, is a robust and lightweight tool designed for plumbing and pipework applications. It offers professional strength and durability while being nearly 40% lighter than comparable cast-iron models.

This wrench features an I-beam handle with a full floating forged hook jaw for superior gripping and quick adjustments. It also includes self-cleaning threads with easily replaceable hook jaw, heel jaw, and spring assembly. Special hook and heel jaws are included for plastic-coated pipe.
