Trim rings for the gold & platinum V2s. Doesn't come with screws, you will need to utilize the ones on the original subwoofer. For mounting Resilient Sounds V2 models with trim rings, we recommend a hex head screw(Last picture) that avoids flaring to prevent cracking the trim ring. The hex head will evenly distribute the pressure to the trim ring reducing the risk from cracking unlike a flared screw.
