Going back a few years I did a couple of jobs where I used Lutron IR controlled dimmers where the back of the dimmers was a clear plastic so the flasher eye could actually be placed on the back of the switch. From what I gather Lutron no longer makes this switch can anyone recommend a similar dimmer product that can be IR controlled from the back side?
One thing I have learned in this industry. It is easier to pull a wire than it is to push one.

The problem with those (and why I think no one makes anything like that anymore), is it means you have a low voltage wire coming into a box with line-voltage. Which is illegal per NEC code.

So I don't think you will find anything like that anymore.

I was thinking the same thing last week. Found pretty much nothing. Lutron's Spacer system seems to have been brought down to the consumer level and that's it.

The elimination of the clear back version doesn't surprise me, the basis of a clear back means that an IR sensor is in an electrical box with 120 VAC wires... Not a good practice... We always used them in a VERY neatly packed J box with a tiny hole in the back. The IR blaster lived on the back of the J box and shined through the hole.

We haven't needed them in several years. RA2 systems with an IR Keypad, or the URC/Lutron cobranded dimmers did the trick... Now we have two simple systems that need one controlled dimmer. RA2 is overkill, URC's cobranded Lutron dimmers are gone. The existing spacers don't have a neutral wire so LED's are a pia... and they're line of sight only (unless you get raeally hacky with them.

We did a few of these also. We had a retro keypad next to the electrical j-box.
We actually mounted the flasher outside of the electrical box where the wire went in. little squirt of silicon to hold it in place. This passed code and worked great. Electrical inspector gave us a pat on the back for being innovative.

Drill a tiny hole in the front side of the light switch and glue the naked emitter to the Decora cover plate.

Keeps your LV wire outside the box, and it actually will work.

Ask me how I know...

There used to be an exception to this rule as long as the low voltage conductors are 1) used to control the high voltage device, 2) they are rated to 600V and 3) are kept 6mm away from high voltage connections.

Not sure if this went away with new version of the code. Anyone who installs Lutron Homeworks Wired Maestros should know for sure.

I used to drill a small hole in the back of the work box and fire the ir through the hole. With the back being clear out usually worked like a charm and kept the lv wires out of the box.This guy just has an old mx3000 with an older base and was looking to control a couple of dimmers. I think i might just price out doing dummy companion dimmers in the theater and mounting the spacer master dimmers next to the rack and putting the flashers right on the front
