Roller shade springs can look similar but may differ in small details such as the presence of a fixing pin, which affects compatibility. Since Elkhart RV Parts stocks Irvine Shade brand springs, if your original springs are from a different brand like MCD, the replacement springs might not match perfectly. To ensure proper fit, please confirm the brand of your roller shade springs. If they are Shade, you may need to source springs or additional parts specific to your brand to get the pin fixture. Identifying the correct brand will help in selecting the right replacement springs that include the necessary pin for your RV's roller shade holder.
