For an in-ground basketball hoop to be worthy of the Goalrilla name, our engineers know that durability, safety, and arena-quality play are musts. The classic GSII has each one of these Goalrilla traits built in. Featuring a 60″ x 38″ backboard, the GSII offers excellent rebound with 3/8″ thick tempered glass. The GS II uses a crank actuator to adjust the goal from the NBA and NCAA regulation height of 10′ to safety-approved height of 7.5′. The included pro-style breakaway rim is a spring-activated rim that flexes under pressure, similar to professional-style rims. This basketball goal offers a revolutionary anchor bolt mounting system allowing you the option to unbolt and relocate your system if you move homes. With its powder coated finish and corrosion-resistant hardware and rock-solid one-piece 6″ x 6″ steel pole, the GSII is one of the family of true Goalrilla outdoor basketball hoops.
