How big is the inner hole diameter?

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

sure, it is 2 and a quarter inches , approx. these are great for runway cones ( R.C. aircraft ) to keep the airplane going straight , so it doesn't bash into the curb ! the hole in the top equalizes the air pressure to keep it in place , a most amazing invention --- take care !

Just received one today and measured the diameter. It will fit in a 9/16" hole.

The inside diameter of the hole is approximately .725 inch, also there is a .425 in diameter post in the center of the .725 hole. hope this answered your question

Inner diameter measures about 2.5". The stable frame itself is made from solid metal which is maybe 5-6mms.

Inside diameter of the nock hole is 0.190". The vanes are pvc, but break fairly easy. The shaft is aluminum and the tip steel. I've had many vanes snap off from just hitting a box filled with towels.

Not sure on accuracy as I took the measurements with a ruler, but here we go: outer diameter is 3 1/4", inner diameter is just over 2 1/2".

I just happen to have this product handy, still in the package, so I know it's the one you are questioning: Answer the inside hole is exactly 4".

I do not know the exact diameter, but I drilled a bigger hole to fit, what I think is, a regular ball.

A standard 4" hole. Due to the construction I'm fire it would a 3.75". It's pretty tight. I cut out some of the rubber that holds it in place with a knife. You could trim it more to fit a smaller hole. I'm pretty sure it would fit snuggly in a larger hole.

The inside hole is 2.5". These are good heaters. I've had one for years now and it still works fine. I bought another one last year for a second bird bath.

I'm sorry for the delay, I've been out of town and unable to measure the center hole. The hole is 1" approx

Offhand I want to say 5/16 or 3/8 inner diameter. I'd just wait for it to come and measure to be sure since different types of tubing stretch differently. But I do remember I was able to easily get something suitable- it wasn't a weird measurement or anything.

Outer diameter is 24mm, inner diameter is 17.5mm with about 3.5mm depth. These measurements should give you a few options.

About 5 inches between holes but the holes are small. Not sure how to answer your diameter question.

As I measure it on an unused tip, the inside diameter is 3/4in. Hope this helps. MB

I don't have an accurate enough ruler to tell you, particularly since you're dealing with at least 2 measurements: the diameter of the internal hole in the tip, and the diameter of the overall tip. Did you try calling Powerline and asking?
