SUPER HEAVY DUTY! A NOTICE. The foot pedal is NOT a brake. It fixes the wheel in one of four positions. That's all. Good product. I put it on a Rubbermaid cart and now it's a tank. Update: They are very durable though. They are very noisy because of the REALLY cheap bearing in the wheel. As you slide down the tiled hallway, you interrupt all conversations and forget to speak to the person next to you.
