A 45 RPM record adapter, also called a spindle adapter, is a small plastic or metal insert that fits into the large center hole of a 7-inch 45 RPM vinyl record, allowing it to play on a standard turntable spindle (which is smaller) for 33 1/3 or 78 RPM records. These adapters, with classic "spider" designs or sleek modern versions, enable smooth, stable playback, preventing slippage and ensuring proper alignment for DJs and music lovers.

Key Features & Function

Enables Playback: Converts the large center hole (1.5 inches) of a 45 single to fit the smaller spindle of a home turntable.

Stability: Keeps the record centered and stable during rotation, reducing pitch variations and protecting the needle.

Material: Commonly made from durable aluminum or lightweight plastic (like polystyrene).

Design Variations:
Spider Adapter: The iconic yellow plastic design with prongs for easy grip and stacking.

Solid/Dome Adapters: Aluminum or plastic discs with a raised center for quick placement.

Usage: Placed on the turntable spindle first, then the 45 RPM record is placed on top, allowing the player to function correctly.
