The Shade Pro system components are not fully compatible with the Valu-Line RV roller shades and their parts, including springs and aluminum tubes, are manufactured by different companies. Because of this, the replacement spring you ordered will not fit your existing 62-inch aluminum tube. Instead of replacing just the tube or spring, you will need to order a complete new shade kit that includes the correct aluminum tube to match the 0.75" version spring of 24" length. You can quickly build and order a compatible new shade kit through Elkhart RV Parts’ online RV window shade designer tool. This ensures all components fit properly and will resolve your repair issue efficiently.
