Description
These vents have been designed to be inserted into a 40mm hole, suitable thickness of container / glass 3 – 10 mm depth.
They will clip into each other, just add some mesh, and glue to secure all in place.
If you purchase with mesh, this is fly proof to prevent fruit fly escapees but will need to be cut to size using sharp scissors.
Custom depths and sizes can be made to order, please contact us via the Ask a question button.
