BD-3 Features: Adjustable to fit each person"s height. H-frame bases allow for a stable stance while in use and safety catch bars are available for emergency needs. Rubber end caps provide added protection and stability. Logic and common sense needs to be understood when raising the bar supports to a higher position while also adding more weight. The leverage support factor is not in your favor the taller the posts are raised, along with more weight being added. If you are a tall person, over 6", you may want to consider other squat stand options from Valor.
