Rockwood Ultralite RV Roller Shade Spring Replacement Guide

The reported measurements do not identify a confirmed replacement spring. A 23-inch vinyl dimension, a reported 3/4-inch “core” and an approximately 15-inch spring are different measurements; they do not establish finished shade width, tube outside diameter or the spring's engagement profile. A Rockwood Ultralite coach name does not choose between Slow-Rise and Valu-Line mechanisms.

The black and clear dials are a useful identification clue. Irvine's Slow-Rise operation sheet identifies a clear upper-stop adjustment and a black speed adjustment. Those controls should be compared with the actual labeled assembly; they are not generic tension knobs that can be disregarded, and their appearance alone does not prove an exact model or replacement fit. Do not apply adjustment or disassembly directions until the mechanism is confirmed.

Irvine's manufacturer replacement guide separates Slow-Rise, 1-inch Valu-Line and 3/4-inch Valu-Line parts. Our 3/4-inch Valu-Line spring reference carries native SRS-SR18S/L options, while the Slow-Rise spring reference carries RS-SR31XS/S/SM/L options. These references identify distinct catalog families; neither is approved for this shade from nominal measurements alone. Do not infer that Valu-Line is correct from a coach price or assume that a similar spring length means interchangeability.

Identify the manufacturer/model and revision, then compare tube outside diameter and end-on profile, original spring markings and end fittings, the dial/control assembly and finished shade width. Treat a finder result as a candidate to verify against that evidence. The failed component, exact spring size and required hardware remain unconfirmed; a new spring is not a guaranteed way to restore holding or retraction.
