Malco C5R 5-Blade Pipe Crimper

In the past used tricks like trimming the pipe and folding inward. Wanted to improve the outcome and process which guided me to crimper. With the reviews and price difference I bought these crimpers. Absolutely impressed!! Crimpers are very smooth to operate. Was surprised at how little you needed to squeeze the handle to achieve a factory looking crimp. Was able to crimp a female end on duct boot and turn into a male end. The fresh crimp slide right inside another female fitting and looked very professional. Also worked great for customizing straight pipes with joints. Highly recommended!!

I'm *not* a ventilation guy, but occasionally I need to crimp some ends for fitment on some ductwork. I didn't like that other much cheaper crimpers were randomly mashing up my duct fittings and not giving me the outcome I needed. The Malco for some reason just gave me better results, has nice sharp interlocking blades (probably it's best attribute) and gave a better result than all the others I've tried. The most frustrating thing you can experience when doing that ductwork is a tool that will not perform up to expectations, and this seems to be a buy-once kind of tool. I was recommended this tool by my ventilation subcontractor and have not been unsatisfied with it since. Just open your wallet and free that trapped money ;-) Seriously though, if you can afford it, this is a solid choice and will not let you down, give consistent results and result in less time spent bending tin, compared to others I have had opportunity to try. I hope this helps.

This was exactly as described, a hand tool you can quickly and easily make a crimped end fitting
