Custom RV shower doors from Elkhart RV Parts are designed for precise fits, but occasionally manufacturing errors can occur, such as rails being too long. In this case, the top and bottom rails of your custom shower door are about 1 inch too long. You have two options: if you are comfortable using a light-duty saw to trim the rails yourself, this can be a quick fix. However, understanding the need for a clean, factory-style finish especially for full-time RV use, Elkhart RV Parts offers a free replacement of the correctly sized rails. Replacement rails will be cut in-house and shipped at no charge. This replacement order covers only the rails, not the full shower door. Once the replacement rails are shipped, tracking information will be emailed to you. If you need assistance with returns or further questions, the customer support team at Elkhart RV Parts is ready to help.
