Tama TTL10 Tension Rod Tuning Locks - 10x Lug Locks (new)
The Tension Lock is an accessory that prevents tension screws from loosening during play. Simply place on the head of the screw, the shape will fit perfectly. On the other hand, the drum can be tuned - thanks to the elastic O-ring around the hole - without having to release the tension lock. A little accessory that any drummer will appreciate.
