IMO the trouble with bi-fold doors boils down to the expense. They are harder to make and consequently more expensive.
The point in the bi-fold doors is that a door that is hinged on the top in a trap tall enough for bobcat takes too long to close and it requires a longer trap unless you are going to use swing doors (doors that are outside the trap when set).
I find you can get around these problems by hinging the door on the side (narrow trap is fine for bobcat). That makes for a wide but short door which closes quick and because my traps have inward folding doors it keeps the trap shorter.
I see no problem using a double door swing door trap or guillotine double doors but since I started producing my folding traps I would not want to go back to ones that didn't collapse because of the bulk. If you built a double door guillotine trap that collapsed I cannot see how you could make it work without some field assembly. Not a fan of that. It seems I remember there was a guy making collapsible swing door traps but I forget who.
Bottom line is you can use one of my traps or Comstocks on its side and you get the height for a cat set. They work perfectly fine that way and it is simpler then a bi-fold trap.
As for using them as blind sets that way, I find few places where I trap to make that kind of set. I know a lot of guys in the desert country use that kind of a set so not dismissing that. I just don't use it much because of what i find in my area.
I own a few from Comstock. Haven't used them yet but they work well when triggered manually. The trigger/latch system is ingenious! Thumbs up to Jim.
Having everything inside and the unique trigger system makes it pretty full proof if covered with a tarp.
If the cats will push on the trigger??? It will be a winner.
I have no problem getting them to push on the trigger. That should not be a problem.
