I have come across a chicago type bender made by Enerpac. It looks to be for 1/2"-1" RMC. I have been all over the net looking for info about it but have come up empty. It looks like it works okay and he wants $50.00 for it. I would like to find a manual for it if possible. I found an operators manual for a Greenlee 1800. Does anyone know if is similar to the Greenlee?
