My dad and I pulled a 1.5 Hp sub pump this weekend and used this clamp for the first time. I cannot begin to describe how much it helped using this clamp. I can’t describe how much this clamp helped. It took all of the work out of the job. I never write reviews, but I am so impressed with this clamp that I had to comment. If it would have cost $1,000 it would have been worth it!
