With out the screw cap on, what is diameter of the opening?

The hole measures 51.9mm (about 2 inches). The threads fit nalgene wide mouth caps, and is thus compatible with most portable filtration systems.

It should fit that opening, but if you can not use the screw options do not buy this product. The Velcro does not hold.

3 and 1/2 inches from the base and perhaps another inch for the screw. Good luck.Ilko

I think there is a small screw that holds the cap in place. I'm not home so I can't check mine out. Sorry.

Are 1/4" 20 to 3/4" the correct dimensions for the adapter screw? I can't find that part. Thanks.

I knocked the dust cap off and measured the inside diameter of the hub where the cap pushed into. Fortunately you only have a few size to choice from so it makes it easy to determine the size.

If I remember correctly the actual opening is 8". I ended up not using it because the opening was described as 6", I believe.

The diameter, on top, from flange end to flange end is 9 3/4" The opening diameter only on top is 8 3/4" - as I measure it..

It is the opening size. However the flange around the dome is not as wide as the original equipment at least in my case.

The bolt (screw) circle is 11 5/8" so the hole diameter should be about 1/2" smaller than that or NO BIGGER THAN 11 1/8" otherwise the screws will have nothing to screw into. You can probably get away with using only 4 screws at 12-3-6 and 9 O'Clock. That's what I did.

Predrill hole 1/8 inch or 9/64 depends on screw that's in it. Then screw in

The opening at the top is 4 3/4 in diameter and the opening at the bottom is 2 1/4 in diameter. Hope that helps

that is very close to the size...mine is installed/sealed, so can't measure for you.

It's about a half inch. I couldn't screw my light cap on because of the raised parts so I marked the circle of the light cap and notched out the raised part so that the light cap sat down flush with the bottom of the unit. Fits snug and looks great! Good Luck with yours.

The cap is 1 & 3/8 inches in diameter. It has 3 plastic prongs on the back that snap into the 7/8" diameter overflow hole in the sink. I purchased this cap to cover the overflow hole in a generic sink. The cap didn't really fit well. I suggest not buying it unless you have the exact sink for which it was designed.

The fan has a length of 33mm. You can measure the length of the cap depth. Thanks

I have several of these, but never had any problems. Have no idea on the size of the screws. SorryAce Hardware has a great selection on screws, perhaps they can help you.
