How do I measure my RV roller shade for a replacement spring?

Measure two things. First, the outside diameter of the metal roller tube the fabric wraps around: it will be 3/4 in., 1 in., or 1-1/4 in. Second, the width of the shade from left to right. The tube diameter tells you which spring family you need and the width tells you which length.

Which Irvine Replacement Spring Fits My RV Roller Shade?

Direct Answer

Match the roller tube diameter first, then the shade width. Irvine uses three tube sizes and the spring is not interchangeable between them. A 1-1/4" tube is a Slow-Rise premium shade. A 1" or 3/4" tube is a Valu-Line shade. Once you know the tube, the width of the shade from left to right tells you the spring length. Every spring below is $49.97 and ships from our warehouse in Elkhart, Indiana.

Model year matters on the 1-1/4" spring. The Slow-Rise spring above is specified for 2019 and newer premium shades. If your shade is older, measure the tube and call us before ordering — we will confirm the right part rather than let you guess.

How to Measure

1. Measure the roller tube. Take the shade down and measure the outside diameter of the metal tube the fabric wraps around. It will be 3/4", 1", or 1-1/4". This is the single most important measurement — a spring from the wrong tube family will not fit no matter what length you order.

2. Measure the shade width. Measure the fabric left to right, not the window opening. Use the chart above to pick the length.

3. Order the matching part number. If your measurement lands right on a boundary, call 574-675-6919 and we will tell you which one to take.
