The Bison Ultimate 42" x 72" Clear Board Basketball System BA873 is the closest thing to gymnasium quality for outdoor play. A 42" x 72" full regulation backboard in tempered glass or unbreakable polycarbonate, a 6" square 3/16" wall pole buried 40" into the ground, a 60" or 72" safe play area setback, an outdoor breakaway goal standard, and an unconditional lifetime warranty on the Ultimate goal. One configuration. No height adjustment. Built, in Bison's own words, for courts where you never want to buy another basketball system again.
The BA873 uses a full regulation 42" x 72" backboard in either clear tempered glass or clear unbreakable polycarbonate. The glass backboard delivers the true rebound response, optical clarity, and playing feel that players experience on a gymnasium competition board, brought outdoors on a permanent installation that can absorb years of hard play. The polycarbonate backboard provides the same 42" x 72" regulation surface area in a material that cannot shatter, making it the right choice for outdoor courts where glass breakage from impacts, weather events, or vandalism is a meaningful concern. Both materials deliver the visual clarity of a clear backboard and the full playing surface of a regulation-width board, with no steel or acrylic compromise on rebound response or sight lines.
The BA873 is built on a 6" square 3/16" wall 2-piece pole and extension arm buried a full 40" into the ground for what Bison describes as incredible stability. The 6" square heavy wall spec is the same structural foundation used across the entire Bison Ultimate fixed height lineup, engineered specifically for the lateral load demands of a full 42" x 72" regulation backboard on an outdoor permanent installation. At 550 lbs, the BA873 is a serious permanent system that ships by truck and requires professional installation with proper concrete anchor preparation before assembly begins.
The BA873 is the only system in the Bison Ultimate fixed height lineup covered so far that offers a selectable safe play area setback at the time of purchase. The standard configuration provides a 60" setback from the pole to the active playing zone. For courts where additional clearance between the pole and live play is required by facility standards, safety guidelines, or personal preference, the extended 72" setback option is available. Both setback lengths carry the same full system specification with the only difference being the extension arm length between the pole and the backboard mount.
Every BA873 ships with an outdoor breakaway goal as standard. On Bison Ultimate systems with steel backboards, the fixed Ultimate goal is the standard inclusion. On the BA873 clear board system, the outdoor breakaway goal is standard across both glass and polycarbonate configurations, providing the rim protection that a premium glass or polycarbonate backboard investment demands across years of active outdoor play.
The Ultimate goal on every BA873 carries Bison's unconditional lifetime warranty, the strongest goal warranty in the entire Bison lineup. Where Bison's Limited Warranty covers damage during normal and intended use, the unconditional warranty removes the normal use limitation on the goal itself. For a permanently installed outdoor system on a demanding court, an unconditional lifetime warranty on the goal is a meaningful long-term assurance that most competing systems at this price point cannot match.
The BA873 offers optional backboard and pole padding available as add-ons at the time of purchase. For outdoor courts with active daily use by players of all ages, padding is a meaningful safety upgrade that protects players from direct contact with the pole and backboard edges during live play. Adding padding at the time of purchase is significantly easier than retrofitting after the pole is permanently set in concrete.
All four configurations share the same 6" square 3/16" wall 2-piece pole, 40" ground bury depth, outdoor breakaway goal, unconditional lifetime warranty on the goal, and truck shipping. Select your backboard material and setback length at checkout.
