I am selling a set of 5- IR emitter covers

This cover is a great way to block out noise and interference from signals and it can help focus the IR signal to the front of the device's IR input. Can be used in any home or business that has  remote equipment and uses IR extenders and/or emitters.

Made of a hard plastic, so it might not fit every IR emitter, it does work with most. 

I use it to make sure that my IRs stay in place in my rack installation or in a cabinet under the TV.
