In my opinion your best bet is a CV enclosure.
A CV enclosure will take CV module and Leviton modules without any drilling needed. Your typical ELK security mounting plates and such all work fine as well. The CV enclosure will not take CV modules without modification.
A Leviton enclusre needs some extra holes drilled for CV modules and needs significant holes drilled for OnQ modules.
An OnQ enclosure will only take OnQ stuff as far as i know.
I own a 42" Leviton and don't own OnQ and CV, but I do have all 3 types of modules in my enclsure and make the above conclusions from examining the pin spacing and pin shape/size.
The CV phone distro module you show looks to be to support line seizing. I have http://www.audio-discounters.com/c-0432.html but i think you already have you phone punched down somewhere and want to patch it do a distro right?
I'm not sure if I was just lucky, but I have a 38" CV enclosure and have quite a few Levition modules in there with no modification. I should have got the 50" CV, but I got a rack for all my other connections instead.
For CATV distro in Leviton, I would use either the 47693-ESM or 47693-3BY if you were going to do some analog camera modulation in the future. Or the two part setup would be 48210-VA and 47690-6C2.
