The Truss Rod Wrench is a 1/4″ socket wrench  for adjusting your truss rod on Deering, Vega, and Tenbrooks banjos.

A Truss Rod Wrench is used to adjust the curve of your banjo fingerboard. The length keeps your knuckles safely away from the peghead. The length, comfortable rubberized handle, and durability let you perform truss rod adjustments efficiently.

Will not fit Goodtime Six String Banjos.
