Zero Manufacturing has a wide range of these things with bolts
holding
down the lids as close as one inch apart to take considerable
pressure.

           Do they have a website Paul ?

      Kelly Troyer

I think they must but I don't know what it is because my catalog is
rather old.
Phone number is (801) 298 5900 or (413) 267 5561

It is Zero corporation and not Zero Manufacturing.

Jerry, here are some 3D's using an all in one alternate air flapper
valve and a Zero
box. 4 by 10.5 by 4 inches high. Part number Z64-168A in 6061-O or
part number ZT64-168B in 3003-O. You can get different style lids with
gaskets
for the bottom. This assumes you are using the up and over manifold.

We might need a group buy on these.

I missed this message earlier and I sent an inquiry about the bell
mouths.  You can disregard it, of course.   What do you think about
just one valve  on the ram air and no valve on the filtered air?
