Review on Secure & Reliable 4 Inch Swivel Caster Wheels With Total Lock - Heavy Duty & 360 Degree Rotation, 1200Lbs Capacity (Pack Of 4) by Viterbo Dashora

I attached them to the bottom of my large firewood box that I keep in the garage under my house. As I need to move the box from time to time it makes the job a lot easier, especially when it's full. I should have done this years ago. These wheels are great at a good price. My only complaint is I had to purchase other fasteners as the nuts and bolts provided were not appropriate.
