Origami 4-Tier Foldable Metal Shelf w/ Wheels

The Origami storage racks are great! I purchased 2 of them when it was offered on Amazon's Gold Box Deal of the Day. I purchased the Origami R5-01W model with wheels because I might occasionally need to move or relocate the storage racks after installation. I purchased one for use in my kitchen and one for use in my home office. The storage racks arrived folded up flat in boxes. Inside the boxes, they were enclosed in plastic bags for protection. After being removed from the boxes and plastic bags, they opened up effortlessly by unlocking a catch lever that keeps them locked together. Once the storage rack is opened, there is a catch lock mechanism located on the back of it that must be engaged to provide stability and complete setup. The storage racks are tall, wide and deep. Each storage rack shelf is about 35.8" wide x 20.85" deep and each storage rack stands 60" high, when assembled. I like the way these storage racks are designed. The quality is actually much better than I expected. They are very well constructed, nicely finished and very strong. Setup was a snap! No nuts, bolts, parts lists or instructions were needed because no assembly was required! I removed the storage rack from the box, placed it on its side, attached the wheels (A double sided wrench is included in the shipping box to facilitate attachment of the wheels to the storage rack.), stood it up on the wheels and snapped the top shelf down. Note: Folding over the top shelf and locking it down while the storage rack is standing up can be a problem if you are assembling it in an area with a very low ceiling. However, if you have this problem, you can easily just lay the storage rack down on its side, fold the top shelf over and lock it down. Then you can just stand the storage rack up on its wheels and roll it wherever you want to position it. A set of four wheels is included with each Origami R5-01W storage rack. Two of the four wheels are locking wheels. The locking wheels help keep the storage rack from accidently moving after installation. I put the locking wheels on the front of the storage racks as shown in the pictures on the boxes. The 4 wheels included with the Origami R5-01W storage rack are a bit small and the maximum weight capacity (storage rack with wheels installed) is 75 pounds per shelf. Caution: This weight capacity must be evenly distributed on the shelf. Place heavier items on the bottom shelves. These Origami storage racks are designed for use on hard, flat and level surfaces. Do not exceed the, maximum weight capacity. If you desire more weight capacity and/or easier movement of the storage rack with wheels, you can easily replace the 4 smaller wheels included with the Origami R5-01W storage rack with a set of Origami Shelf Heavy Duty Wheels. I decided to purchase 2 sets of the Origami Shelf Heavy Duty Wheels because the wheels are thicker, larger and the maximum weight capacity (storage rack with heavy duty wheels installed) is 170 pounds per shelf. Caution: This weight capacity must be evenly distributed on the shelf. Place heavier items on the bottom shelves. These storage racks are designed for use on hard, flat and level surfaces. Do not exceed the, maximum weight capacity. The Origami Shelf Heavy Duty Wheels facilitate easier and safer movement or relocation of the storage racks after installation. Actually, if you want to install the storage racks with wheels, I would suggest purchasing the storage racks without the wheels and purchasing a set of the Origami Shelf Heavy Duty Wheels separately. Otherwise, you might end up with unused sets of the smaller wheels that are included in the boxes with the Origami R5-01W Storage Racks (Like I did). Note: If you have no need to move the storage rack after setup and you do not want to use wheels, I would suggest purchasing the Origami R5-01 General Purpose 4-Shelf Steel Collapsible Storage Rack (no wheels). Installed without wheels, the maximum weight capacity for the Origami R5-01 is 250 pounds per shelf on level surface with weight evenly distributed. It may be a great choice for use in a garage, office or warehouse. The AMAZON Product Information Technical Details webpages do not give accurate information concerning the dimensions of the storage rack wheels. For the wheels included in the box with the Origami R5-01W storage rack, Product Information Technical Detail specifies the following approximate wheel dimensions: (5.2 x 5.5 x 2 inches). The wheels that I actually received have the following approximate dimensions: (3 1/2 x 1 7/8 x 7/8 inches). The wheels including the housing extend approximately 2.5 inches from the bottom of the storage rack after installation. The height of the storage rack with these wheels installed is approximately 62.5 inches. For the wheels included in the box with the Origami Shelf Heavy Duty Wheels, Product Information Technical Detail specifies the following approximate wheel dimensions: (7.2 x 7.5 x 2.8 inches).

The heavy duty wheels including the housing extend approximately 3.5 inches from the bottom of the storage rack after installation. The height of the storage rack with these wheels installed is approximately 63.5 inches. Without wheels installed, the size dimensions of the Origami storage rack when folded are approximately 20 ¼" W x 2 ½" D x 60" high. With the Origami Shelf Wheels (smaller wheels) installed, the size dimensions of the Origami storage rack when folded are approximately 20 ¼" W x 2 ½" D x 62 ½" high. With the Origami Shelf Heavy Duty Wheels installed, the size dimensions of the Origami storage rack when folded are approximately 20 ¼" W x 2 ½" D x 63 ½" high. The Origami General Purpose 4-Shelf Steel Collapsible Storage Racks are a great buy! They are just perfect for my needs. I especially like the way that the storage racks easily fold up and roll out of the way when you don't need them. They take up very little space when folded, yet they provide a lot of storage space when unfolded. I would definitely recommend the Origami Storage Racks to others.
