The interchangable nature of these doors (as opposed to the more fixed hinged doors) make them the perfect, flexible option.
I can see why Architects of Destruction chose this model as their sort of go-to dungeon door.
Having used both hinged and the slide in/slide out style, I much prefer these with actual gaming play at the table, as the swinging door creates a bit of an annoyance when actual miniatures are standing around them.
Interestingly, you might get some great market synergy off of these doors being fully compatable with AOC’s.
They’d give all of the backers of that Kickstarter increased options for the doors they already own.
