Summary
| Description |
English: In some regions, 7-inch 45rpm records were sold for a 1/4 inch spindle with a knock out for playing on a 1 1/2 inch hub. In contrast, in the US for example, the default hole was for a 1 1/2 hub. To play the latter on a 1/4 inch spindle required the insertion of a device called a "single puck." |
