Hi there, Thanks so much for reaching out about your concerns. If you are looking to purchase a trim kit, I recommend checking out SamsungParts.com or calling 1-800-627-4368. If you're having trouble installing the trim kit, we suggest working with a professional installer for further assistance. You can check with your retailer about installation professionals, or you can use the following link to locate a service center in your area: https://www.samsung.com/us/support/service/locations/
However, if this does not help, could you please provide a little more detail on what information you are looking for?
