This heavy-duty unit has several adjustable features, including the main uprights which have 10 different heights ranging from 37.25” to 61”. Additionally, the safety catches, used in the event the lift cannot be completed, adjust from 19.75” from the floor to 31.75” with 7 adjustment positions. The base for each upright also adjusts from 20” to 28” – for a standard Olympic bar, an ideal distance between the uprights is 28”, making for a total unit width of approximately 56.5”. At the top of the uprights, the J-hooks feature a locking bar catch. This feature is extremely useful when users are changing plates by ensuring the bar is locked in place. This is also useful when the unit is not in use. Space always plays a factor in any home or light-commercial gym. With the nesting storage feature, these independent stands can save a lot of space in your fitness environment when not in use.
