Adapter for Headless Guitars for Standard Wall HangersThis adapter is designed to offer a secure mounting solution for most 6-string headless-type guitars (without a headstock).Key Compatibility Measurements:For a perfect fit, we recommend verifying your neck dimensions. Keep in mind that most 6-string headless guitars have approximate measurements of 50 mm at the top and 40 mm at the bottom, which makes this adapter compatible with the vast majority. Top Width (Outer Limit): 52.39 mm. Inner Neck Width and Front Stop (Support): 42.49 mm. This is the narrowest part that holds the base of the neck. Total Width for the Headstock: 19.56 mm. Intelligent Design for Maximum Hold:In addition to dimensional precision, the piece has an angle in height that utilizes the guitar's own weight. This ensures a better fit as it lowers, guaranteeing that the neck remains firm and secure in the support.Product Features: Material: PLA (high-quality 3D printing)
