This was a great addition to the storage cabinet. The assembly was very easy to complete. If you have the extra height, it adds much more storage space.

Damaged order, not faulting Sams but 1 cabinet was unusable after unpacking it. Although still waiting from Sams for directions after opening a claim. In all fairness I have purchased 14 cabinets with only one arriving damaged.

I absolutely love my Seville Ultra HD garage cabinets! So much storage and now with this additional space on top I am able to get all of my stuff put away organized! Love it!

This add on cabinet makes a great addition to an already great cabinet. Looks good and adds more space to make it a supersized storage cabinet. Same great quality and features as for main cabinet. Highly recommend!

Very well made and fits perfectly came with additional screws in case one was bad

The Seville Classics® UltraHD® series cabinets are an excellent product. They are easy to assemble and very well packaged for shipping to your home. I do recommend using a cordless screwdriver or drill set to very low torque for assembly vs. using a manual screwdriver. The shelves are plenty strong provided you use them in accordance with the directions! (Do NOT stand on the edge of a shelf like one reviewer mentioned her boyfriend doing, and then left an unfair negative review.) Total approved weight per shelf must be evenly distributed, not all in one small spot. I also like how easy it is to place the shelves at different heights depending on how much clearance you need per shelf. I did end up ordering one extra shelf direct from the manufacturer. I also purchased ten stacking storage cabinets and built a custom hardened steel storage support system so I could place them high up on my wall, as opposed to stacking them on large floor cabinets. This took some time to build and weld, including modifications to the corner support brackets, but in the end it looks beautiful and works perfectly and safely. I would definitely purchase more of these cabinets.

See attached before and after pics. Very easy to assemble.

As always! Excellent quality, easy instructions and great design.

Adding bonus storage to your storage cabinets - an excellent upgrade.

Pleased with the additional storage specs it provides.
