This Kahler 6 string guitar string cage comes assembled with 6 string hooks and a pin. The 3 included mounting screws attach it to the cam and 6 fine tuner knobs (sold separately) screw into the top of it.
The string hooks, which the ball end of the string drops into, are housed inside the cage and held in place via a long pin that can only be removed one way.
Fits all cam based Kahler tremolos (2200, 2300, 4200, 4300, 7200, 7300, 2330 Flyer, and the Gibson Super-Tune). Some older models have a single piece cam that integrates the cage, this cage is not compatable with that cam but it can be replaced with the modern cam design along with this cage.
