Subject: RE: Flat rails Part #2

From: "Crawley, Eric" <esc@...>

Yes indeed! Letting the screws go into the wood a tiny bit seems like a no
brainer to me. If 10ga steel can still be cut by normal humans, with hand
tools, then I think we would have a solution that would work for any size
cabinet. I think that 10U is probably the best general size but that could
go shorter or longer as needed. You would just order enough segments for
your cabinet and cut them to the size needed.

The important thing is to have the rails drilled for flathead wood screws
for attachement (and tapped for modules).

Thanks for listening gang.
