I bought the Post Cap to replace an original equipment cap that deformed with age. The installation was easy, but had to be modified to fit an eye screw on my original equipment. Drilling a 1/4 inch hole in the back to allow for the eye screw took 10 min for both end caps. When complete the new cap fit perfectly, held the net at 42 inches at the post and easily allowed adjustment to 36 inches at the center. The cap has performed beautifully holding the net in place and shows no sign of rust or wear. Recommend for replacement caps on a 3.5 inch round pole.
