2 sets of commercial grade shelving units, heavy duty build, great for a retail space or the garage. They are one wheels and include adjustable shelving brackets. They are good condition and still roll well. I used these in my store for a while but needed to rearange things for efficient use of floor space. Perfect for organizing a garage as a rolling tool storage or organization solution as well as retail shelving. Will need a truck and help to move them. Pick up only.
