Elkhart RV Parts can accommodate custom window shade requests; however, the manufacturer’s maximum size for pleated shades is 76 inches wide, and roller shades can only be made up to 80 inches wide. Since your requested 86-inch width exceeds these limits, a single custom pleated shade of that size is not currently available. One alternative is to order two smaller shades to cover the larger window side-by-side. To proceed, please provide specific details including size, color, material, shade type (pleated, Valu Line, or Slow Rise), and quantity so an invoice can be prepared. While fabric size restrictions limit single large shades, Elkhart RV Parts remains open to exploring other options to best match Irvine Custom Pleated Night Shades and ensure your RV window coverings are cohesive and high quality.
