1-Inch Diameter Shade Spring & Roller Tube for RV Awnings | Elkhart RV Parts

A reported 1-inch tube diameter, 42.5-inch tube length and 23¾-inch spring length do not establish an exact replacement. First identify whether this is an interior roller shade or an exterior awning, then match the manufacturer, mechanism, tube outside diameter, spring end profile and applicable part number. Tube length, finished shade width and spring length are different measurements; do not treat them as interchangeable or assume that a nominal 24-inch spring matches a measured 23¾-inch assembly.

For an identified Irvine Valu-Line 1-inch window-shade system, the manufacturer's chart groups springs by shade width: Small 20–29 inches, Medium 30–59 inches and Large 60 inches or more. Our 1-inch Valu-Line spring listing currently offers MRS-SR25S and MRS-SR25L. A confirmed crosswalk from those two catalog options to all three manufacturer categories and to the assembly described here has not been established. These are identification references, not approval for an awning or a specific fit.

No expedited service, shipping charge, dispatch date, holiday arrival date or discount policy is confirmed by this historical answer. Review the current options for the exact item and destination when ordering; do not rely on the old dimensional or shipping assurance. Identify the assembly before loosening a tensioned spring.
