I hear alot of people say that the E-Z con. are no good, they loosen-up, or what ever. I use them on everything, and at both ends. They are fully adjustable and E-Z to use. I have always said One could wright a book on the art of tightening things. I always hold the body of the E-Z con. with needle nose pliers or something to tighten them, and I'v not had any loosen yet.They are just a piece of hardware, it's all in how you use it .
