Top mounting bracket

A home owner from 94704 says:
Hello Swisco,

I am looking for a top mounting bracket that is currently being used with a Grant (pc 23-189 ) four wheel trolley. I can find no markings on the bracket so I am not even sure it is manufactured by Grant? It is 3.5" wide x .75" deep.

Can you help identify?

Hello, Niko. Our 23-162 is similar to yours, and is meant to be paired with the 23-161 four wheel pocket door carrier. Please compare this to what you have and let me know what you think.
