Single Rim Rod Set for Banjo

Installation and adjustment instructions for a Single Rim Rod Set for Banjo.


This is a modified Gibson-style rim rod design, for 11"-diameter open-back banjos, or for banjos which do not use a Gibson-style one-piece resonator flange.

The location of the upper neck attachment bolt is determined by the neck attachment hole in the tone ring (Gibson-style flathead or archtop tone rings) or it can be located below the tone ring (Whyte Laydie, Tubaphone or rolled brass tone rings). To install a neck purchased from us, align the bottom of the fingerboard (the fingerboard/neck glue joint) with the top of the tone ring.

Transfer the neck attchment bolt locations to the neck heel, by marking them through the holes in the wood rim. Drill two 5/32"-diameter holes in the neck heel and install the neck attachment bolts.

Drill an 11/32"-diameter hole in the wood rim for the rim rod. The rod should be parallel to the bottom of the rim.

Minor adjustment of string height above the fingerboard:

  • To raise the string height, loosen hex nut (B), tighten hex nut (A), and retighten hex nut (B).
  • To lower the string height, loosen hex nut (A), tighten hex nut (B), and retighten hex nut (A).

Do not adjust more than 1/16" in either direction, to avoid unnecessary compression or possible delamination of the wood rim. Insert a nail in the small hole midway on the lower rim rod, to prevent the rod from turning while making adjustments.
