Choosing the Right Replacement Spring for Your 20-Inch RV Roller Shade

Asked by MaryAsked on May 27, 2025Answered by Elkhart RV Parts
Customer Question

Is the 0 to 40 inch replacement spring, which measures 24 inches end-to-end, suitable for my 20-inch ISD brand roller shade? If not, what spring size should I use?

Expert Answer

A replacement spring measuring 24 inches is generally designed for roller shades wider than 20 inches, so it may be too long for your 20-inch ISD brand shade. Using a spring that is longer than the shade width can cause improper tension and affect shade operation. For a 20-inch roller shade, it is recommended to use a smaller spring specifically sized to match that width range. We suggest obtaining a spring designed for shades around 20 inches wide to ensure proper fit and function. If you received a spring that is too long, you should exchange it for the correctly sized replacement. Our customer service team can assist you in selecting and shipping the appropriate spring for your shade model.
