Elkhart RV Parts offers Dometic dual pane window click stay hinges compatible with various RV models. For replacement windows, please specify your RV model and window measurements for an accurate match. Regarding slide-out springs, the value line spring generally provides standard tension, while the slow roll spring offers smoother, controlled extension and retraction. Since your slide-out has a 34-inch tube and 31-inch width, ensure you select a spring matching these dimensions. We recommend contacting our experts with your RV details to confirm compatibility and receive personalized assistance in choosing the correct spring and window parts.
