The Pearl Spin-Tight Drum Key is designed to work specifically with their Spin-Tight Tension Rods (unveiled early 2014) that lock in place with key-within-key technology!
Inside the standard rod chamber is a small hex key that fits into the hex screw on the top of each Spin-Tight Tension Rod. This hex key can be tightened independently from the rest of the rod, effectively 'locking it down' so it won't loosen up under hours of heavy playing.
This drum key acts just like any other key when used on other standard tension rods.
