The Dunn-Rite PoolSport Backboard (part BB900) is the OEM replacement backboard for the Dunn-Rite PoolSport pool basketball system. When the original board cracks or yellows from UV exposure, this replacement restores the unit without replacing the whole hoop. UV-stabilized materials resist fading in full-sun pool environments. Will this fit your hoop? Please read this first. This board fits the Dunn-Rite PoolSport. Dunn-Rite backboards are not interchangeable between models. The rim bolt pattern and the post bracket pattern are different from model to model, so a board from another unit will not line up and cannot be made to fit. How to identify the PoolSport board. It is a rectangle with rounded corners, 22" wide by 31" high. White face, blue target square, "PoolSport" logo in the lower left corner. If your board is a fan shape, wider across the top with curved sides, it is not a PoolSport board. Not sure which unit you have? Ask us before you order.
