If your double slow rise RV roller shade only stops about 2 inches before fully rolling up and doesn't hold at other positions, the issue is usually related to the internal spring tension or how the auto-stop engages. Since you've replaced the stop assembly, it's likely the spring may no longer hold enough tension or the stop isn't properly seated inside the shade tube. We recommend checking the spring condition using our replacement spring checklist available on our website. If the spring is weak or damaged, replacing it with a compatible RV roller shade spring will restore proper stopping functionality. Proper installation of both the spring and stop assembly ensures the stopper can engage anywhere along the roller, allowing you to set the shade at any desired height. For assistance, you can review our spring replacement guide or order replacement springs directly from our RV parts collection.
