The Mass Storage system is full commercial grade. This is the real deal with hardware to match. Note, these units are HEAVY and are easiest to assemble with a second pair of hands (my son helped me). Good value at the price point and the Free Shipping created the value I could not pass up. I am very happy with the system and will be ordering additional pieces as I grow my home gym. One Note: Wheels are not currently offered but it you want them they are available from other commercial suppliers just make sure you purchase wheels with the correct bolt pattern and weight rating for this application. X-Training...please add a wheel package that possibly even widens the base. Thank you.
