This Hosco Steel Two Way Truss Rod has a low-profile design (just 9.5 mm deep) meaning only a small amount of wood needs to be removed to create the truss rod channel, allowing you to carve thinner necks if you wish. It has a two way double action design allowing you correct both up bow and back bow and it is available in two lengths 460 mm and 360 mm, the 460 mm length is great for electric guitars and the 360 mm length is great for acoustic guitars. The truss rod nut adjusts with a 4 mm allen/hex wrench (not included).

The truss rod should be installed into a flat bottom, straight channel with the static flat bar upwards (against the fretboard) and the rotating rod and adjustment nut below, no filler strip is required between the truss rod and the fretboard. Please take care to ensure no glue runs in to the channel when gluing on the fretboard.
