Measure for Skylight Replacement

Needing to replace skylights. Looking at Home Depot, I'm not seeing proper replacement sizes. However, I want to confirm I'm looking for the right size. I measured the box on which the "cap" or skylight sits. See attached pics for those measurements. Based on what I'm seeing, should I be looking for a 26.5 x 50" replacement or is there something else I should be measuring to ensure I get the correct replacements?

Home depots site mentions:
  • FCM 2246 models are Designed to fit a site-built curb (not included) with outside dimensions 25-1/2 in. x 49-1/2 in.
This model would sit on top of that size curb.

This is the flashing kit for such a curb.

Whether or not your existing skylights are curb mount or deck mount, I can't say based on your photos.
