What is the outside dimensions of the vent and what is the screw hole spacing?

Vent cover is approximately six inches square. Screw holes are six inches apart (horizontal) and 3.75 inches apart vertically.

13x2 is the size vent that I use my fan on. It doesn't quite cover the length but I covered the excess with a small piece of magnetic sheet (refrigerator magnet)

14" square is the standard opening and this vent will fit like the oem vent. Note that it does not come with the necessary caulk seal for around the roof hinge, but I picked some up at the local auto parts store when I installed mine.

I do not recall the dimensions but I do remember that they were larger than my existing piping (non-CARBON compliant). The muffler shop that installed it for me had to fill the gap with weld.

Installed, it is just a hair under 11 1/2 inches x 7 1/8 inches. The holes are elongated, so if you need the flap lower or higher, there is some wiggle room when attaching it

External dimensions are 6 3/8" wide by 6 1/2" high. This is the overall size, not the hole size. The recess is approximately 5" wide by 5 1/8" high.

The spacing between screw holes is about 2 inches. Note that it does not come with the screws to hang it!

Fan itself is 10" . The holes are on 12 1/2" circumference. Or the holes for mounting are 1 1/4" out.

Ours is sealed in installed and we cannot measure the outside dimensions. Soud be in the product description if not on Amazon then at another vendor. Sorry.

about 28 inches. Add 5 1/2 inches if you add second piece with the side vent holes showing.

The vent's width from end to end is 19" and is currently fitted on the outside of an irregular opening leading to a crawl space. It is secured with two threaded bolts with clamps which secure the vent to the inside wall. The vent's dimensions suggest that it would fit comfortably on the outside of a hole left by the removal of a 16" block, not the inside. I hope that helps if I understood your question correctly.

The inside dimensions (that fit into the duct) are 13-3/4 x 3-3/4. Outside dimensions (metal part) are 15-3/8 x 5-1/2.

The opening (to the shed) on the bottom of the vent is just over 8 1/2 inches square. This gives you the 75 sq. inch area. Overall (flange) dimensions are about 13 inches square if I remember correctly. BTW, I really like the vents, they let in more light than I expected !

Just measured it, and it's about 20mm. The gap is for proper air flow so you don't have any over heating. The total height of the unit measured from the mounting surface is about 70mm.

16 high, 24 wide and about 15 deep. Those are actual dimensions, so I'd add an inch to be able to let it vent.

It is 11 1/2 inches on outside edges and about 10 inches on the inside. I am using it on a wider vent as well(under a dresser) and it stays in place and works, not 100 % but better than if it wasn't there.
