Order Replacement Black Roller Shade for Grand Design 2670MK RV

These details are useful for identification, but they are not sufficient to confirm an exact replacement or order size. A Grand Design 2670MK model name does not identify the shade maker, mechanism revision or mounting clips. Keep the reported 26⅛-inch gear-to-gear width, ¾-inch tube diameter, one-inch mounting plate and 25 × 26-inch window measurements separate; they describe different parts of the installation.

The current Irvine Valu-Line Night Roller Shade is a custom shade to investigate, not a confirmed direct replacement for this blind. Irvine's Valu-Line reference shows several mounting systems, including mounting clips, spring clips, flat brackets and two L-bracket styles. A one-inch plate dimension or a similar tube diameter does not establish that the existing top clips will fit the new shade.

Do not round 26⅛ inches to the nearest selectable width and assume it will fit. The current builder offers width fractions in quarter-inch steps; it cannot represent ⅛ inch exactly. First establish whether the required order width is the finished shade width, bracket-to-bracket space or a different measurement under the selected mount instructions. Measure the usable space inside the valance near the mounting position, note obstructions, and record the required drop from the actual mounting position. The window's 26-inch height alone does not establish the finished shade drop, and order notes do not resolve a conflicting selected size.

Use the original shade label and photos of both ends, tube, mounting hardware and fully extended shade to identify the system. Confirm the intended fabric and rail colors separately; “black” does not identify the mechanism or mounting arrangement. Until the exact shade, measuring convention and hardware are matched, the proposed width, drop and reuse of the existing clips remain unconfirmed. The earlier assurance of a precise compatible replacement was too broad.
