I got them years ago, so i don't know how readily abailable they are now. The 7" rack was fairly easy to get, from Juno I think.
The 10" one next to it is actually for 12" records (no one makes 10" racks") i bought that off Ebay 2nd hand, i'm guessing from a record store that had closed down?
I modifed that 12" rack to fit the 10" records so they don't fall out.
All the LPs behind the decks are sitting in 12" racks to hold them together.
I removed the black paint off them and sprayed metallic purple to match my mixer cause i'm sad like that .
Still need to do the same for the 7" though
