Description
 
This grommet is sized for a 3/4" Hole in a surface UP TO 1/8" thick. When set into a 3/4" hole, the inside hole measures 5/16". You CAN push a 3/8" diameter object in, such as a racking cane with a little effort but a nice firm seal. We use this to put our TW18 thermowell into the lid of a bucket or fermonster. You can force the inside hole to be a bit smaller, closer to 1/4" if you intentionally under drill the large diameter hole to 5/8" or 11/16". It will take more effort to get the grommet in, but it will work.

5 of 5 Good product, 11/16" hole required February 20, 2020
Reviewer: Daniel L. from Atlanta, GA United States  
This product works exactly as advertised, but I ended up using a step bit to drill out my fermenter lid to 11/16".  A 7/16" hole is too small to fit the whole piece through.
