These are excellent for customers that are storing warehouse or retail inventory, as you can line both walls with shelving units or pallets and have a path to walk down the middle. These would also be good for mechanics needing access for power tools, restaurant suppliers, appliance repair and storage. We also have clients that have large DJ/music production companies, and they use the unit to store all of their equipment and have a staging area for the employees to pick up what they need for each job. We also have some units that are more budget-friendly and still allow for large storage space. We have jumbo units without power and with manual doors available as well at a lower price. These doors are individually keyed with a standard garage door T handle and do not require an exterior lock. These are excellent for customer that are storing work trucks and supplies, construction businesses, classic vehicles, and large furniture items (including customers that purchase storage auctions for a living).
