Jeeze mkoloj, it's refreshing to find somebody who shares my point of view. I catch flack every time I say what you said about using a backboard and that those structured wiring panels are junk.
Anyway, check Clifford of Vermont. They now handle a large part of the Emerson Electric line which was Reliable Electric. The telco closure that you are looking for traditionally has a plywood backboard to make mounting blocks and fastening cables easy. There is the indoor/outboor line in 3 sizes- BUPNP-1,BUPNP-2 and BUPNP-3 and the locking RC1212S and RC1824S.
