I bought these to put gorilla shelving in my basement. Most reels like this are quite expensive, but it's a good price. They're cast iron, so I wouldn't use them on finished surfaces, but they're great for my basement and garage. Smooth wheels, smooth turning, very strong (can bear a lot of weight compared to rubber wheeled counterparts). I've bought about 30 of these now and think they're a good product that I would recommend.
