Looking to move your basketball hoop with a 7-Inch anchor kit? Ensure that your hoop is compatible by measuring the distance between the center of the anchor bolts (see picture). If the measurement is 9 inches, then you need the Goalrilla anchor kit. This 7-Inch basketball anchor kit is a direct factory replacement for Silverback, Goaliath and Hoopstar goals. Includes steel plate, J bolts, nuts, washers, and rebar steel rods to strengthen concrete.
