A 45 rpm adapter or adaptor is a small plastic or metal insert that goes in the middle of a 45-rpm record so it can be played on the standard size spindle of a turntable. The adapter could be a circular shape like this one that fits onto the spindle or a larger adapter that fits over the entire spindle of a record changer. This is an iconic image from the age of vinyl.
