Mounting of DIN Rail Dimming/Switching Modules

For the LQSE-4A1-D etc., I am wondering what enclosures anyone out there might be using for these. Internet searches have not been productive. I am hoping to find some sort of recessed metal, (or plastic), enclosure that still has the front exposure for the center section of the module. All I am finding are plastic surface mount enclosures. The Lutron enclosure for the DALI and ECO modules is not rated for dimming modules, as it does not provide the necessary low VS line voltage separation or protection.

The reason this came up is a couple of projects we are doing really would benefit from locating "local" dimming modules in closets etc. as wiring to a central location is very difficult. In the past we used WPMs, but with all the LED fixtures, and more importantly retrofit LED lamps, we are finding it necessary to use adaptive modules almost exclusively, which eliminates the WPM as a realistic solution. Without an "in wall" recessed solution, (no interior designer we have spoken with would ever sign off on the surface mount options), we're stuck with ganging up a bunch of individual dimmers, and that's just not a solution.

Try Pragma flush mounting from Schneider Electric. They do a 1 row 13 unit wide enclosure.
