Tube Cap Grooves: 49.5mm in diameter to fit an industrial paper towel tube.
TP Tube Cap: 43.3mm in diameter to fit standard toilet paper and household paper towel tubes.
Extra Hook: A few people mentioned having a problem with their hooks, so this is a hook that you can glue onto a previously printed cap.
