These will fit into a 6.5mm slot rebated into the guitar neck before fitting the fretboard.
This is dual action rod. It can be bend the neck in either direction to ensure the correct releif along the length of the neck.
 
We use these rods in our own necks and they work very nicely, giving a nice, uniform curve when under tension.
