One set of 12 PDP nylon washers for tension rods. It's the finishing touch on you replacing your tension rods. They fit both the PDP Standard and PDP True-Pitch tension rods. They do a great job of not adding anything to the natural shell vibration and have the incredible benefit of being easy to seat and smooth to turn. Quality rendering.
