You can never trust a measurement that's read from a tape measure in a photo, unfortunately. There are too many factors that interfere. Take a look at the 18-196 sash guide pair to see if it matches your dimensions. If it doesn't, then type out the dimensions of the part for us, so we know how it differs. |

Hmm... to be honest, I think you'll be fine. I don't think a 1/16" less on the top cap width would hurt in the operation of the window. |
