For your Salem 30kqbss travel trailer's slow rise roller shade, we offer replacement springs compatible with Valu-Line Roller Shades, featuring a 0.75" diameter and capable of extending from 40" upwards. To find the exact spring you need, please provide the SKU or the dimensions of your broken spring unit. You can browse and purchase replacement springs directly from our online store. Regarding the adhesive tape for reattaching the shade material to the tube, we recommend using a strong double-sided tape suitable for RV shades, which we can help you source if needed. While warranty replacements depend on the original manufacturer, we can assist you in obtaining the correct parts for repair to restore your roller shade's function efficiently.
