I'm sure there are many posts out there on this but my searches have come up empty.
I'm in the process of running 6" PVC around my shop and am looking for alternatives to using 15+ wye's. I thought I'd seen a plan or pictures on here a year ago where someone built a plywood box that contained 2-3 blast gates. This is exactly what I could use at multiple locations as I've got three spots where I'm dropping a single line down from the main trunk. Each of these drops will need to service 3 pieces of equipment. I'd much prefer to do something that's an integral wye and blast gate than purchase this many wye's. Another negative to all these wye's is they take up a tremendous amount of space.
Ideally the solution would be something like this but with a blast gate on the 3 ends.

Please post pictures or links if you've got them. If the above item is available in a 6" version I'll consider getting them unless they're extremely expensive.
Thanks,
