I attached the galley hatch side trim pieces. These include the side trim, and an aluminum strip under the hatch lid that the weatherstrip will be glued to.

Next steps are to attached the 1" aluminum angle using 3/8 rivets. I'll also trim out the interior with 1/2" aluminum angle and then install the hatch light. Then the hatch goes on the teardrop.

The straps are to insure the hatch does not "relax" and spring out of shape before being installed.
