Tension Rod Washers from Danmar are t-shaped nylon discs that are mounted on your tension rods - before you mount them on your drum - so that there is no metal on metal contact.
This gives you a range of advantages.
As soon as you mount your Tension Rod Washers, you will feel the difference. You will feel how the tension rods turn in a much smoother and more comfortable way when you tune your drums. This is because there is no more metal on metal contact between the tension rod and the rim. The Danmar discs eliminate the rough and hard contact between the metal tension rod and the metal rim. Furthermore, the smooth feeling when tensioning the rods gives a more precise tuning of the drums.
Note: Tension rods are not included. Only the colored nylon discs are included in the package.
