What size is required for the attic opening?
922979
Finished opening minimum of 15" wide by 21" deep. Note that because this doesn't just fold and swing into the opening (it telescopes and then slides up and back), ther is additional clearance space required inside the attic behind the ladder.

My opening is 15'8" by 6'11" It was alittle log but he height was good. It's going to be long for you but the right height. Feel free to ask me more.

In response to your question, this item is generally 8 inches by 8.5 inches if I remember correctly. In either unit that you decide to buy keep in mind as I learned these items are meant to be installed from the attic for a perfect fit. My attic was inaccessible; in my case, I went in through the bathroom. I did have to make some incisions for the tabs to slide in but they were not visible once the outer circular cover is installed. I must want you. Be prepared for the unexpected. In my case my electrical wires were too short and there was not exhaust hose leading outside of the attic. You only need this hose if you will be using it to extract moisture. In response to your question, this item is generally 8 inches by 8.5 inches if I remember correctly.

You will need at least 3 square feet, up to 4 square feet. It can be configured many ways depending on how steep the zip lines are! Luckily Pollys don't get hurt.

I am using a standard gable vent spanning the stud distance of 16 inches. I think the vent is about 24 inches high. That works great for my garage attic.

The rough opening is 17 1/4" by 17 1/4". For more info go to http://www.bvc.com/Installation%20Instructions/IF%20Oper%20Instr.pdf,

Diameter is about 13.75 " across. There are 4 angle brackets spaced evenly apart for mounting. You can either put it on a flat surface and mount like that or put it in a hole and mount it for recessed mounting. I mounted mine in the gable opening with plywood and a 15"hole. love it. works great. Keeps attic cool

The opening in 4 inches in diameter. You will have to be the judge on this issue.

Yes... the opening on the base of the device is approxim,ately 12 inches in width. The hole in my roof was approximately this size. Also, get some longer screws or roofing nails, as those provided are too short. Finally, get a few tubes of Henry's roofing tar/adhesive to properly seal around and beneath the solar attic fan.

The opening (which is square) in the closed position measures 1.25 inches between the corners, 1 inch between the sides. That would be the minimum opening size. The mechanism is adjustable to larger sizes that would appear to accommodate frames of almost any size (at least several inches in diameter). The carriage of the assembled stand using a back pack would be awkward in my view.

The maximum opening for this hardware is 40". I would recommend the door hang over 1" on each side which will require a 38" slab door for your 36" opening. But it can hang over as much as you want, any door between 36"-40" would work.

You will need two if you want to use the full 6ft opening. Total length required is 144". Make sure you have 36" on either side of opening to accommodate door and rail.

You need a track that's more than double the width of the door in order to open it all the way and have room for the door stops. So probably 84-86" minimum would do. This track is too short for that. You can put any door pull on you like, don't have to use the one that comes with the set if that's what you mean by the hardware

It's 13 x 13 3/4, Bitsy. It should cover your opening but you may need a small piece of sheetrock depending on the mounting. It's a nice fan/light.
