You can start your return by using the provided return label available through your Elkhart RV Parts account. Since you are exchanging for the correct hinge, the 20% restocking fee has been waived and shipping costs covered. Additionally, the manufacturer confirmed that the hinge is reversible and can be used on either the bottom left or bottom right by flipping or turning it, making separate left or right versions often unnecessary. If you decide to reorder, the original hinge is still available on our site. For detailed compatibility or further assistance, you may also contact the hinge manufacturer Lippert directly. Please let us know how you'd like to proceed, and we'll be happy to assist.
