Hello - what is the diameter of the opening? Thanks!

The circular opening in the back is 3 and 7/8ths in diameter and has four positioning screws.

Sorry for not responding sooner. I'm measuring the diameter and I get .040". I hope this helps.

I don't know the exact measurement but the canister isn't tapered and doesn't bottleneck. The opening is the same size as the canister itself.

I agree with Gerald Clare. The opening narrows slightly from the top to the narrowest width. I measured 7 cm at the top and 6.7 cm at the narrowest width would be a good estimate for me.

The diameter is about 4 inches. It's the perfect size - not too big, not too small.

Mine measured at about 2.25 inches diameter of inner opening, the base is about 7.5 inches diameter. Hope that helps.

I'm at work right now but I would say the opening is a little over 3 1/2 inches and it is about 7 inches high. Hope this helps.

The top opening is 2 1/2 inches. Be careful when you fit the lid on. the lid holder does not go on any old way.

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 on mine is 3/4", though is could be a little bigger since the stopper is angled.

I did not measure, but I am sure that 2" will be to large of an opening, since it has a nut that screws in from the back to secure it in place and that nut I would estimate a about 1 1/2"

Yes, the opening is much larger than a normal one. Over 5/8 in. In diameter. JDW

I don't know the exact size, but the opening is about the size of a quarter

It is just under 2 1/2" outside diameter, with a ridge a little way (1/4") down from the opening. Then it gradually tapers out to almost 3". The actual opening is just about 2 1/4" wide.

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).
