Product review (3 stars): Be aware of modification needed
It is not clear on the description, but this bracket is made so that one of the axles of the Metro Master Blaster, not the hand handle, rest on it. It is necessary to modify the axle for that and the hardware for it is included in the package. However, if one changes the wheels of the Metro Master Blaster, this bracket may become unusable. That was my case. I have changed the wheels that come with the blaster (which are pretty bad - the only bad thing about it, actually) and could not use the bracket at all. It was returned.
