These are perfect replacements for Ovation guitar factory strap holders. Ovation supplies guitars with just the base part that screws into the guitar, if you ever need to replace or want to change colors, these are the ones. One caveat, the supplied screws are wood screws, Ovation uses an insert molded into the fiberglass bowl, that accepts a machine screw. Don't use the wood screws supplied with the straploks, its the wrong pitch and the wrong thread type.
