Medium Universal Stopper - Drilled
well made & durable , I did have to drill it out about 2mm bigger to fit the 3 pc airlocks I purchased . I assume it was predrilled for the S type airlocks , and I had to modify my fermenter ( a 5 Gallon water carboy of unknown origin ) as it was to small a opening , My fault as I forgot the ole adage , measure 2 or more times Cut once (lol ) so If I had ordered the carboy from Midwest it probably would have fit out of the box ! but it works great
Folks! It's nothing more than a typical stopper!
This is an A-1 stopper!!
