36" long magnetic strip designed to use in setting letoff on grand or vertical pianos. Strips available in either 1/8" or 1/16" thickneses. Please choose thickness below. Strip will stick to plain wire strings. You can then set the letoff at 1/8" or 1/16" by adjusting the letoff screw so the hammer just touches the strip before letoff. If you purchase both sizes you can achieve a 3/16" letoff distance by putting the two sizes together.
