When I picked this tool up on a buying trip in Europe I knew I had to bring it home for you. Then I gave it to a plumber friend and said, "Have some fun". His critique, "I want one". The spring-loaded jaw allows for a quick, snug, triple-point grip around any pipe measuring up to 1 5/8" diameter. Much faster and easier to use than a conventional pipe wrench. Amazing gripping power! Ideal when stuffed under a sink or in a tight, spider infested space. Hardened steel jaws and a forged steel handle. 12" long. Buy two so you can steady the pipe with one while turning with the other. Keep a small repair from becoming a huge one! "Hey Joe, may I please have my wrench back?"
