The Power Station is a variation on the usual cage theme. Designed to allow unrestricted overhead barbell work, the Fat Bar Power Station is a 3133 Power Cage with maximum headroom. One pull-up bar is 1¼ inch in diameter, the other is the 2 inch Fat Bar for increasing grip strength. Constructed with 3-inch, 11 gauge tubing with a durable powder coat finish, the 3171 is ready to suspend the weight of your choice. Features include chrome-finished, welded weight storage and the strongest welded J-hooks in the industry. Open top design gives you all the headroom you need for overhead exercises. Extra versatility is afforded in that all hole spacing is two inches center-to-center.
