This T-REX spring assisted portable is the same system as our popular main court T-TEX 96 but with a shorter extension from the base. That makes it a nice size for a side court system or home gym. Built for aggressive play and excellent playability at rec centers, practice facilities, multipurpose sports centers, church facilities or anywhere a durbable, easy to set-up basketball system is needed. Rim height can be adjusted and locked in anywhere from 7' to 10' for youth league play. This portable is a great system, shop around and compare these features. Extension spring adjustment system makes for a 5 min. set up by one person. This no maintenance spring system is much better than leakly hydraulic systems used on other brands. Rim height adjusts anywhere between 7' and 10' for youth league play.
