Cant' place facades on rednet energy cable

[ghost]

Title pretty much says it all.

I tried the (oak wood) facade from BC Transport as well as the facade from AE2. I can't seem to attach any of them on a rednet energy cable (while they work fine on the me glass cables).

I can attach the covers from FMP, but that doesn't really solve my problem since they count as a block themselves which means i can not place a block directly on it the way I need to.
