For an inground basketball goal to be worthy of the Goalrilla name, our engineers know that durability, safety and arena-quality play are musts. The GS-II has each one of those Goalrilla traits built in. From its 60" x 38" tempered glass backboard (tempered glass is used in pro, college and high school systems) to its powder coated, rock solid one-piece 6" x 6" steel pole, the GS-II is a true Goalrilla outdoor basketball goal. And just like every Goalrilla unit, the GS-II's height adjustment actuator makes this unit one accurately adjustable basketball goal. We never compromise what it takes to be a Goalrilla.
