Solid aluminum 45 rpm adapter for playing 45 rpm records. A new manufacturing process has yielded the best-looking adapters yet! Absolutely stunning finish (highly polished and smooth as glass!). Cone-shape design makes it easy for DJs to quickly play 7" records. The hole diameter is machined to the PERFECT size to fit on the turntable spindle without any "wiggle". We haven't seen a higher-quality adapter.
