How to hold wire going outside

[Ryland]

I just drilled through for an outside light and the outdoor box that I have doesn't fit the normal 3/8 wire clamps that I have used everywhere else. What should I use to A hold the wire tight and B make it weather tight?

is it 3/4"?if so you can get a 3/4 clamp or if you don't want to use that big of clamp,get a 3/4 to 1/2" threaded bushing.then you can use the 3/8 clamp.

The hole in the box is 3/8" but the threads aren't the same as the clamp.

Nevermind. I just didn't align the clamp right. Its in and fine, thanks.
