The Silverback SB54iG, our premier in-ground basketball hoop, features a tempered glass backboard and powder-coated steel pole that is directly installed into the ground and secured by concrete. The SB54iG uses a crank actuator to adjust the goal from the NBA and NCAA regulation rim height of 10 feet to the safety-approved height of 7.5 feet. The SB54iG comes complete with a pole and backboard pad to offer protection during lay-ups and a break-away rim that flexes under pressure. Backed by a 5-year limited warranty, the Silverback SB54iG is a perfect hoop system for your family.
