87" H|48" W All-Metal Garage Shelving Unit and Storage-Easy Assembly Shelves 5-Tier Rack|Heavy-Duty Adjustable Shelf|Steel Waterproof Rust-Resistant Shelves for Industrial,Warehouse,Basement

Very well constructed and sturdy shelves. Easy to put together. They are very adjustable. Really like them.

Caster mounts made of plastic. Had my stereo equipment on the rack. Moved it out from the wall and the plastic caster mounts broke dumping thousands of dollars of stereo equipment on the ground. Shelfs sagged with weight. Do not buy unless you like ruining your stuff.

Decent shelves , fairly strong, and easy to assemble. Would be much stronger with thicker gauge material and metal inserts/joiners in lieu of plastic. If you think you are going to store more than 30lbs and use the rollers, forget about it. The wheel housing/inserts that are installed from bottom are plastic (see pic) and obviously don’t handle much weight.As stationary shelves they are fine, but as rolling shelves is a joke!

Product is not as good as it seems in picture.
