Tension rods beware. You're about to get quickly removed by the Gibraltar R-Class E Key Drum Key.
This drum key makes rod removal and replacement quick and easy. It fits the hand (hence the "E key" which stands for "ergonomic") nicely.
This key is also available in heavy die cast or light weight styrene and is even able to be made for left or right hands!
Bonus: there's a key ring on the end, so no more hunting around for lost drum keys!
