Thanks for your question Guy.
This Rubbermaid 7580-L2 Red Wave Brake Quiet Caster is a replacement part for WaveBrake mop bucket.
Do you have a product number for the brute dolly you're referring to? With a product/model number we can track down the appropriate caster. Please give a member of our Tundra Restaurant Supply team a call at 1-888-388-6372, and we'll be happy to help find a set of casters that'll work for you.
