Tama TTL10 Tension Lock (10pcs/set)
KEEP DRUM HEAD TENSION WHILE PLAYING
The Tension Lock is an accessory to prevent tension bolts from loosening while playing. Simply set it on the tension bolt head – its unique shape fits perfectly. On the other hand, you can tune the drum without having to detach the Tension Lock, thanks to an elastic O-ring around its hole. It is a small accessory, but filled with TAMA's unique ideas.
