If the slow-rise roller shade components you received are too large for your tube, it’s important to verify the exact make, model, and year of your RV to ensure compatibility. Since your camper is under a year old and manufactured by Forest River, providing these details will help identify the correct replacement parts. Measurements alone may not always guarantee a perfect fit due to variations in tube diameters and shade models. Contacting the manufacturer or dealer can sometimes clarify part specifications. Once you provide your RV's make, model, and year, we can assist in selecting the appropriate premium slow-rise roller shade components or replacement springs that match your specific shade tube size. If an incorrect part was shipped, we can arrange an exchange or refund to resolve the issue promptly. For best results, also check the total length and diameter of your existing spring and roller tube before ordering replacement parts.
