How high is the side brace and how wide is this between legs front to back my console door is 19 by 40

Hello, The width between front to back leg, outside to outside, is approx. 34.75" wide. The height of that first cross bar is approx. 36 1/8". The standoffs do not have to mount to that first cross bar if they are not the same height. They can connect to the console and one of the legs if needed. You just want to ensure you get the standoff as high as possible for better stability.
