All New Mammoth Basketball Line from Lifetime Products. Bolt-Down Anchor Kit Included! With some major improvements, the 90965 takes you above and beyond the previous Mammoth Basketball Line. The 90965 provides ample playing room under the backboard during your game. The new Mammoth basketball line also has an improved height-adjustment mechanism called the Mammoth Pump, that allows the user to easily move the backboard up and down using a single handle. Simply squeeze the trigger and the user effortlessly moves the backboard height, changing the rim height from 7.5 feet high to 10 feet high in infinite increments. Order your Mammoth Basketball System here today. 

The Mammoth® huge steel backboard and real glass surface give you the look, feel and power of the pro game! Tempered glass and hardened black steel are fused together to withstand even the harshest of elements. The massive one-piece pole has been moved to the front of the anchor-plate to minimize wobble and pole vibration. The imposing pole-anchoring system has a unique bolt-down design that allows for precision leveling, and when it's time to pack up the herd and move, you can detach the anchor system and take it with you! The high-performance Spring-Flex™ rim features a continuous net hook wire, which secures the heavy-duty all-weather nylon net to the rim with minimal resistance. The double-compression springs allow you to slam it like a pro!
