This was an additional component that I purchased for a specific purpose with limited space.  I finished my entire three car garage with Gladiator products. I've also used their products for storage in both my basement and attic. I've utilized pretty much the entire product line ( cabinets, flooring, work benches, shelving, bins, baskets, hooks and track wall from floor to ceiling).  Great products! Easy assembly! Top quality! I've looked at many garage systems. Whether it was the DIY products to the companies advertising complete garage make overs, Gladiator Products far surpassed the competition. 
Best products on the market! Excellent customer service!
