I didnt think I was clear there :)
What I mean is theres something like 18 1/2" of space for the entrance when turning the entrance the long way. Making an 18 1/2" reducer with the standard slot sizes isnt a big deal. What Im wondering is 18 1/2" too much to guard when fully opened? Standard way the entrance is 14 3/4" or so.
It doesnt seem like a big deal, but Ill be painting them Sunday and want to get it all worked out.
If you look at trailtwisters pic on the stickied post youll see the entrance is around 6". Ive seen other pics with the same. Thats what got me to wondering.
