A110 Flute Pad Backing Washers
Ferree's has just a few metal flute pad backing washers. The A110 washers come in six different diameters and are .016" (.41mm) thick. These washers are similar to the washers that K.G. Gemeinhardt Flute Co. once used as a backing in their padding process.
The A110 Metal Washers are sold by the dozen and available in the following millimeter diameters;
18mm is all that is left.
Soon all the original millimeter diameters; 16,16.5, 17, 17.5, 18, 18.5 will be available in a plastic washer.
