Nicot system on peirco frame

[slacker361]

do you just secure it with rubber bands?

[AllenF]

Sounds like it would work.

I would cut a space to put it in...

I'm with Michael.  You need to cut a space so you can access both sides.

Better yet would be to put it in an empty medium frame.  There are screw holes in it to mount it to the top bar.  I find it more versatile in a medium as I can use it in any brood chamber (medium or deep).
