J-Hooks are located at the top of the uprights to safely rack the bar during squats. The safety catches adjust from 22” to 36” from the floor. To adjust the position of the 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 stand is also adjustable and 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 storage pegs enhance the stability of each stand. To perform bench presses, create enough distance between each stand to allow enough room for an individual bench to easily slide in. Be sure to adjust the J-hooks and uprights to a height the is close enough to the bench to easily rack and unrack a barbell. With a maximum weight load of 350 lb directed downward, the BD-8 Independent Squat Stand Towers is an ideal addition to any home or light-commercial gym.
