I have a large diaphragm U87 type condenser mic which I've owned for over twenty years. While it still does its job nicely, the elastic cords for its shockmount were completely worn; dangerously so. I ordered these and they are the perfect replacement for the old ones. In fact, I feel they're even better because, while fitting nicely, they're a bit thicker than the original ones, so less flimsy and hence less prone to move. It also means they're a bit tighter, which also helps to keep the spider in place without sacrificing its vibration prevention ability.
