We worked with an American rubber manufacturer to make a better grommet. We've been very happy with the results and so have our customers. Here are the key differences:

• Thicker rubber for less distortion and even positioning
• A tighter fit for better dampening and sleeving
• A longer neck which hold the springs in place
• Made in the USA
