MA71260 Klenk Five-Blade Offset Crimper

I'm a union sheet metal worker and of all the pipe crimpers I've tried, these are some of the best. No other pair I've come across provide such a long and deep crimp as these do. The only issue I have [and it maybe a big one for some] is that the spring inside the tool seems to have a shelf life of only 2 to 3 years as this is my 3rd pair in 5 years. Be that as it may, that still does not detour me from purchasing them but it is something to keep in mind if you plan on purchasing a pair for yourself.

This is a very good tool. I used it to prepare ducting for the dust collection system in my shop. It's easy to use, even for 70 year old arthritic hands. Gives a great result and very quickly. It was recommended and offered by my source for ducting parts, but available at Amazon for nearly half the price.

My son loves the crimper. He does duct work for a big heating and AC company. They do what they are supposed to.

Just what I needed to fit 3 inch water heater vent pipe. Easy to use. good quality tool.

Quality item that performed better than expected. Would recommend.
