Kegco wall mount drip tray question

[audiophool]

I decided I need a drip tray for my keezer. 4 taps with 4" spacing. I am interested in this model: https://www.kegco.com/draft-beer-equipment/drip-trays/sewm-1610-4 but the published specs do not give the hole spacing for the taps. Apparently Kegco doesn't know either, because when I contacted them and asked, they referred my question to the Amazon community, and said I was unlikely to get an answer since there was no response in the first couple of days.

Does anybody out there have a Kegco wall mount drip tray? What is the hole spacing on yours?

Thanks,
Mike
