Fit perfectly

Holds seal perfectly.

perfect fit had no problems no water leaks . would buy again if needed .

I need 1 rubber grommet but 1/2 OK

Solid and well made, measurements are right on spec

These are the cheapest way to add a sight glass to your bucket

Great product Easy to install with 13/16 inch bit and no leaks

too small needed much bigger
