Shubb Capo Replacement Sleeve and Cap Set Don't throw away a "Mercedes" when it just needs new tires! Replacement sleeve for model 2 or 3 (nylon string or 12-string) 2.25" also fits C6b, dobro capo. Extra long so it can also be trimmed to work with shorter 6 string and banjo capos. The Delrin cap can also be a retro-fit for older capos that did not include the Delrin cap.
