Can anyone give me advice on using velcro for an enclosure door? I think it would be strong enough to keep my ig's from getting out...... but, not sure?
Any advice would be greatly appreciated. Thanks.

The question is too general and depends on several variables including but not limited to:

1) size of the iguanas
2) size of the door
3) amount of velcro used
4) enclosure "fixtures" that the iguanas could press against for leverage

Probably many other factors I missed.....

I am making two enclosures.
One for Ti almost 2 feet
enclosures size is 2.5 ft three sided triangle, the "door" I wanted, would be a flap from the top corner. The velcro is "industrial enclosures" and would be the length of 2.5 ft on one side and 3.5 ft on the other, revealing a triangular opening. I could place the "climbing structure's" to not be to near the flap.
The 2nd one is for Shooter a little over 3 feet he weighs about 12lbs
His enclosure is 4 ft by 5 ft and the same strength velcro would be used. and again a flap from the top of 4 ft by 3.5 ft. flapping down in a triangle.

I feel that making the doors peel down from the top would take away possible stable pushing grounds. and I would arrange the climbing things to not be next to the door?

Does this help?

I have 4 years experience with soft side cages and iguanas -- canvas walls with clear door flaps.

In short velcro is no where near strong enough.

Go take a look at my cages for ideas on door flaps.

Do these guys free-roam at all? I'm thinking these enclosures will be too small for them. The minimum size for an adult ig is 6x6x4.

If you're making the frame out of wood, you can use rope like I do. It works wonders. I tail six nails, three on the enclosure,and three on the door, at the top, middle and bottom. I tie a rope to each of the nails on the door and when I want to lock it I just wind the rope in a criss cross manner like you would a manila envelope. It is so strong that I know if I were to yank on it as hard as I can until something collapses, the enclosure would topple before it opens the door.

As for enclosure size, the one for Ti is definitely too small.
The one for Shooter, assuming it is tall enough, will last you a couple years or so still in my opinion.
