You can return the two replacement roller blind springs that don’t fit your RV blinds by using our online returns portal at elkhartrvparts.com/pages/returns. Once the items are received, you will be issued a credit for the return. To order the correct spring sizes—3/4” by 24” for your 49” wide blind and 3/4” by 14.75” for your 31” wide blind—you can use the pre-created shopping cart link provided by Elkhart RV Parts to easily checkout with the proper springs. Remember to update your shipping address when you place the new order if you are no longer at your campground. If you have any questions during the process, the customer support team is ready to assist you.
