Replacement Rollers

Question

Hello, have Sun Air windows in my house built in 1988. In one very, very big one that has no rollers what so ever! I have attached pictures. Please confirm that the 87-177 is the correct size. Big Thanks!!

I'm afraid that I cannot determine your dimensions from just a photo of a tape measure. The angle at which it is held makes it difficult to confirm precise measurements. However, we have dimensions on the 87-177 store page that you can use as a reference. I will also post them here for your convenience.

As for the lock in your second batch of photos, it looks like it could be either our 90-009 or 90-005. The only difference between these is the style of the "tab," which is not visible in your photos. Look these over to confirm the better option.
