I just measured my Lance 1161 escape hatch (Not a Heiki, thank goodness)
approximate cut out 19 1/2" X 26 1/4"
actual opening 19" x 25 3/4"
=================
Years ago I replaced a 22" x 22" hatch cover on my old camper in it's 15th year with one 22" x 22" x2" thin gauge sheet metal. It was made in a sheet metal shop and had welded corners. It was too heavy for the crank handle that came with the original escape hatch.
I had to open the screen to assist in lifting my home made cover... letting the bugs inside with us... why have screens?
I dug deep and bought a new plastic cover that was made for the hatch.
++++++++++++++++==
Silver... would I have to remove or open the screen to open or close the hatch?
Thats what I hate about the Heiki Hatch... if I have the Heiki hatch open all evening the mosquitos are all arond the outside of the hatch like senior citizens at the Golden Corral.
Get a little cool in the night or a few rain drops... I have to slide open the Heihi Hatch screen to adjust or close the outside of the Heiki hatch cover...
... letting the mosquitos and gnats inside for a gourmet Golden Age meal... me and Janet
Other than that possibility... I sure like the marine grade, locking hatch.
