Yes, replacement tension springs are available for your RV double roller shade. Since your roller tube has an interior diameter of .75", you can order a .75" Irvine replacement spring compatible with Valu-Line RV roller shades. To select the correct spring length, measure the full width of the metal roller tube end-to-end, excluding plastic end caps. You can order the spring directly from Elkhart RV Parts’ website or contact them for phone orders. Additionally, if your shade requires it, auto-stop components are also available as compatible accessories. Use discount code ALIRVP for $5 off your order.
