45 rpm Adaptor Phone Case

A 45 rpm adapter (also 45 rpm record insert, 45 rpm spindle adapter, 7-inch adapter or spider, the common size of 45 RPM records) 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 small solid circle that fits onto the spindle (meaning only one 45 could be played at a time) or a larger adapter that fits over the entire spindle of a record changer, permitting a stack of 45s to be played. These are often referred to as 45 spindles. A few manufacturers supplied a complete change of spindle for 45s.
