1/4". You did not ask, but the thickness is only 1/32". Advertised as "heavyweight" I expected a thicker product.

I do not know the exact size hole. The vent came with a template to cut the hole. My estimate would be approx 3 inches.

hole size is 3/4" diameter and minimum 7/8" deep. Contacts Normally Open. Yes, as it is now the contacts are open.

I don't know and can't measure them because i used them all in a location that is difficult to reach. The hole diameter was about 3/8-inch or maybe 5/16. In the picture, you can see a threaded nut, and that nut screws against a shoulder; therefore, the hole diameter is slightly larger than the OD of the threads.

Diameter of the hole is 1/2". Clip overall is 3-1/4" x 1" wide. FWIW I love these things!

The hole is a bit larger than 1mm. I used 1mm stretch cord to measure and had room of approximately a quarter or half a mm left. I was not able to run the cord through a second time. I hope this helps.

Not sure about that device. But the hole is 9mm in diameter.Edit: In reference to Carey Zeng's comment; The outer diameter is 9mm, then it tapers in to an inner diameter of 7mm. I apogize for the lack of care in my original answer.

I am away right now but guessing 3-4 inches. They have been good ones. Holes the right size.

The Grover web site says they are .39 in. in diameter, slightly larger than .375 in. You may have to enlarge the existing holes.

I used it on a vessel sink, mounted on a countertop. Hole size is 1.25 inches. Mounted roughly 2 inches from the sink.

The hole is 1 7/8. Be careful if you're connecting it to an outlet on the inside that you offset then hole and the outlet itself. they will not fit if they are back to back. I use this for a dedicated heater connection.

Not sure about the hole size. I've had too many different types. Just test drill on scrap wood to make sure you have the right size bit for the threaded nut to fit in.

My husband measured the hole and it measure approx. 1 1/4 inches, this will fit on a light socket with threads on the end of it. I hope this helps you and if you have any more questions please ask
