US Patent 10157630 Record stabilizer for multiple vinyl sizes

In some embodiments, a record stabilizer is configured to fit both common size spindle holes (e.g., as commonly found in 12″ singles or LPs) and larger hole types (e.g., as commonly found in 7″ 45 rpm singles, typically referred to as “45s”). In some embodiments, the stabilizer achieves this functionality using one side that is substantially flat (for common size spindle holes) and another side with a built-in adapter to protrude into larger spindle holes. In some embodiments, the record stabilizer also serves as an adapter, e.g., allowing 45s to be played on turntables with common size spindles without using any other adapter.
