Used the retain the strings inline with your top nut on the head stock of the guitar. Most commonly fitted on the D, G, B and high E strings. This pair are the correct match of 2 differing height trees, the taller 5mm high tree fit the D & G and the lower 2.5mm high one fits the B & E string. The higher tree also has a correspondingly longer screw supplied. The upper part of the retainers holds the string apart by approximately 6.5mm.
