So I needed new rod protection for our trampoline because our goods after years crumbles times and found the original article it too expensive. (Ie = UTF8 & qid = 1424606695 & sr = 1-3 & keywords = rod protection + trampoline). These here are knotless and super cheap! Wen the gray color does not interfere with ... you are still a lot thicker than the colorful from the trampoline accessories. I had to laugh when the truck drove up and gave a huge package. He asked if we had ordered springs ... :))) 60 cents for a trucking delivery? Am very satisfied.
