Question: Will this mounting rail work in a Hubbell HPW78C19X30 rack?
Answer: Thank you for your inquiry, While the 7805-ES2P rails would theoretically work with the Hubbell HPW78C19X30 rack (worst case with custom holes), we are unable to guarantee compatibility as Great Lakes does not specify this.
