The FRM-471 is 16" long and has a 2-1/8 Inch pad width, with black vinyl-finished padding. being slightly wider and thicker than the FRM-473 16" which has the Genuine Leather Finished 2 inch padding. This is especially for small accordions that have at least a medium width bolt-plate for the adjusting bolt.
The FRM-471 is useful for some very small 120 bass accordions, and some larger than average 12 bass accordions, etc. As always, compare the old strap with the one you are about to order. If the strap is anchored internally you can measure the distance between the centers of the apertures, and add 3 inches to that measurement. Any time you get a strap in the mail that is a worngr size, you may exchange it for full credit.
