This is a demonstration of how I have made the assembly of NSF, Trinity, Costco Commercial grade chrome wire shelving racks a little bit easier. The assembly instructions in this video will help you with most rolling wire shelving racks, not just the ones sold at Costco or Amazon. http://amzn.to/1V2PK39 This rolling storage rack is a fantastic storage solution; it is easy to assemble, easy to move around and easy to adjust shelf height.
A great tip for assembling chrome wire shelving racks is to use a box to set the first shelf on wile you assemble the poles. With the bottom shelf on the box you can easily handle the poles and put the wheels on without having to mess with the shelf falling over!
