What is the outside diameter of the opening which attaches to the watering can - 3/4" or 1"?

O.D. is ~1.075" measured with dial calipers and coarse threaded by pressed or rolled method.

It is 1 inch were it screws onto the can.... but it is too big for my can. I need a 3/4 inch. Does that help you?

It is 1" the same as a standard water hose end. I see one of the other respondents used a calipers but this is not a high quality machined part. They are just stamped so each one will have a little variation.

The outside diameter of the 'flange' is 1.75 inches, or 44.45 mm, whichever units you prefer to use.

It has been some time since I installed this for my Daughter, but I think it is 1 1/4", I used an adapter and used 3/4" pipe in our situation, I probably would not use any smaller than 3/4 pipe tho,

The outer diameter is between 3&3/16 and 3&1/4 inch. It varies depending where you measure it.

I measured 1/4" at the opening. There is a little ridge about an inch from one end ( to keep the straw from pulling out)

4" outside diameter. The end nozzle fits most household type attachments @ about 3 1/8".

It is 1/4" & if I remember it has a 1/4" to 3/8" adapter. I use the 1/4" with a long extension and ratchet. Sorry for late reply due to holidays and a good case of the crud. GMF

1 1/2" is the size I used but I had to use a adapter to reduce it to a 1 1/4" to hook into my old black plastic pipe that goes through the wall and leads outside.

The instructions say 1 inch diameter. I believe that was what I used to install it. But the spout fits tightly and is offset in the hole. See my review in installing it.

Correction...upon further review it has a 1" diameter but it comes with a ring/washer to adapt to a 3/4" hole. Hope this helps.

I believe it is 3/4" but already installed it. I have an Orbit Model 55661 in my garage and that is definitely 3/4".

When in the locked position, it is about 1.5" and when unlocked it's about 1/4 inch. It works great on my patio door.

The opening is 3 3/4". I am in Canada and the diffuser I bought is standard and fits the opening well.

Hi Gregory. Don't know if you've already received a response, but the hole needs to be 3/4".

This water dispenser requires a minimum hole of 3/4" and no more than 1 1/4".

The metal circle area for the bottle has a 3 1/2" wide opening if that helps.
