The replacement spring you received may not fit your RV shade tube due to size or assembly differences. To ensure the best fit, it is recommended to use Elkhart RV Parts’ color match service by sending in your old shade. You should send the entire old shade, including the mounting rail, so the team can accurately measure and match the parts needed for your specific model. This service provides a reliable way to get parts that fit perfectly and match your RV’s original shade color. Once they receive, the team will handle the color matching and measurements, helping you rebuild your shade with the correct spring and components.
