Set of 4 "Sphinx" glides. Nickel plated steel glides come complete with black rubber cushions (goes between amp and metal glide). Yes, these feet will fit your old Showman, Bassman, Bandmaster, etc. I measured .994" diameter X .346" tall on a sample. This is close in size to the '60s originals. Made In China by Penn Elcom. Fender does not include mounting screws with this "raw part" but we do.
