Just under 4.5 inches or 110mm. Seems the seller should be answering these questions.

Well, amazon asked me to answer your question since I own this product. However they neglected to send me the name of the product or a picture of it... I'm going to have to guess and say the opening is anywhere between 1/2 an inch to 6 feet tall. Wish I could clarify further! (Amazon... Good idea, but this was poorly executed).

The opening is 7/16 inch, the straws that come with it are quite wide. I use stainless steel straws and they are quite a bit narrower than the opening.

The opening is 5 and 3/4" inches or 14 cms. However after I put my fish that I had for over 3 years in it, 5 days later they all died. Two goldfish and one molly. I washed it out and put the same water in from the Aquarium in it and they died . Hope that helps

The opening is exactly 1.5 inches in diameter. I was able to easily fit my standard umbrella pole into it.

This is designed to fit a 1.7 inch cutout and it has a maximum outside diameter of 2 inches. Unfortunately this will be too small for your opening.

I recall it was about 1-1.13" opening. I stopped using it after about a year when it began to rust

The inside diameter of the opening is 3/4 of an inch. You might want to consider it about 1 mm smaller to allow for the thread space of the screw on top.

I Michelle, I measured about the same - actual opening is slighly less than 6 inches, 7 3/4 inside. This is a great piece. Take care.

I didn't measure the opening it fit in. I just used it as a replacement for the lock/latch in my travel trailer door. After removing the old hardware the new one fit perfectly in the opening.

The inside opening inch is about 2 1/4" in diameter. At the top it is closer to 2 3/4". It's difficult to measure precisely, but I tried to be a a accurate as I could.

The opening is .170 or about 3/16 of an inch. The inside diameter of the neck is1/2 inch. I usually use it with 4 seasons dressing mix and about once a month I have to unclog something. Overall I am pleased with it.

I am not sure how to measure the opening. I use it to feed my fish. It is about the size of a silver dollar )maybe a bit larger is circumference). the opening is cut at a diagonal when I feed my fish I gently tap on it, it and they know to come near the opening to eat.
