Constructed of 2” x 2”, 13-gauge steel, this unit has adjustable uprights with 10 different positions ranging from 49.5” to 75” making this a great product for multiple users. J-Hooks are located at the top of the uprights to safety rack the bar during squats. The safety bar catches are also adjustable with 11 different positions, ranging from 24.75” from the floor to 38.5”. The included bar catches, which is also adjustable, is perfect for resting the bar in the bench press function. To adjust the position of the bar and safety catches, simply loosen the popper pins, pull, and then slide into the preferred position. Retighten the popper pin to secure it into position. The base of each unit is also expandable, with 3 different positions ranging from 20” to 28”. With an expanded foot base, the unit becomes even more stable, if required. Each stand also features a 1” storage peg (7” in length) to safely store standard and Olympic plates for a clean and organized gym. These pegs are also compatible with the Valor Fitness EX-10 Olympic Adapter Sleeve that converts 1” storage pegs to 2” storage pegs. When loaded with plates, the unit becomes even more stable. To perform bench presses, create enough distance between each stand to allow enough room for an individual bench to easily slide in, while the bar rests on the bar catches. With a maximum weight load of 350 lb directed downward, the BD-9 Independent Power Squat Stands is an ideal addition to any home or light-commercial gym with single or multiple users.
