I am familiar with wood "Wire Mold" but I just ran across Electro Trim.

Apparently it was sort of like zip cord but with a 3/16 gap between conductors. Just rubberized cloth in the gap. This was nailed to the wall, and fixtures were made to tap it and terminate it. I have just one part. A tap It is only .8 wide and 2 in long.

Does anyone know any more about this?

I can't help with your question Frank, but I have one for you......

Where in the world do you keep finding such wonderful little goodies? ;)
Grin. My wife gave me a I-pad. I don't like TV but I do like being with my family so I spend a lot of time scanning E bay. Still there is a lot I cant afford or that just gets by me. I spotted this one just a few hrs before the auction was up. There are things like a Chapman plug that I am looking for but don't know how to search because most people wouldn't know what to call them.

Hello Frank,

I'm not wanting to burst your bubble, but have you considered the older 300 ohm TV antenna lead-in wire as a use for this tap? The two wires in a 300 ohm antenna wire are separated by 5/16 inch and look like the picture on the box. Television dealers would have a need for such a device in their display room so they could connect multiple sets/locations to one antenna.

Regards, Dennis

It does look like 300 ohm lead on the box. At home I use to tap the 300 ohm to run to the radios in other rooms.

Bubble is in tack. (Grin) It was being sold in March 1935 Popular science, and I have the instructions for installing.
