Two Struts + Two Knobs
Installation was simple & straight forward, took about 30 min doing it myself. What a difference it makes, mowed during the heat of the day without any problems. I was worried about one area with a lot of tree limbs, it actually made it easier, it allowed the branches to slide up over the top instead of slapping me in the face. This is one tough product. Great product, good price, great people to deal with.
