The new part was not compatible with the original trampoline parts. The end of the pipes have a squared off section that interconnect with one end being slightly larger that the opposite end so that the part can be inserted into the adjacent piece. Original parts will insert and new parts will insert in new parts but new and original will not. I had to go to a machine shop and have them modify the end so that I could mate an new part to the original parts that were still good.
