Stefanoo, the rubber washer fits over the spindle and is 1.25 inches in diameter. It is to be used in conjunction with VPI's screw down clamp.
The washer "slightly" suspends the record over the platter. The screw down clamp has a concave bottom and when screwed down it "cups" the record into contact with the platter.
