433Mhz RF RELAY HOLDER

This is a mounting holder for a 433Mhz RF Relay Board. Because the PCB has no mounting holes and the edges have components very close on all sides I made a special mount and back protector for this relay unit. It will work with the other frequency relays as well. I use 4 #4x 1/2" pan head Robertson screws to mount the whole thing to the wall or joyce. There are some different options, some with labels.
