Z-racks are a must-have resource for any department store. Use it to move clothes in and out of your store, or to effectively manage your backroom inventory. The unique "Z" shape makes it possible to nest the racks together and by attaching an add-on rail, you can double the space. With a 500 lb. load capacity and four 4" solid rubber casters for support, z-racks are perfect for heavy duty jobs.
