These strings are for most lever harps with nylon strings, EXCEPT for harps made by pedal harp makers. If your string list shows string gauges, such as .025 and .040, then these are the correct strings for your harp.
Since each replacement string is 52½" long and some of the higher notes are a lot shorter than that, one length of nylon can be used to string two or three of these higher notes.
Use this list ONLY if you know exactly what string you need. If you aren't sure, please go to the string list for your harp model.
Remember, strings are NOT returnable for any reason.
