DIMENSIONS - Center Hole - 3/8' diameter (9 mm), Center Channel - 1/16' width (1.5 mm), designed to fit 9/16' lid holes (14 mm).
EASY TO INSERT AND REMOVE - Simply punch or drill a 9/16' (14 mm) hole in your mason jar lid and insert the grommet edge into the opening so that the grommet groove catches on the edge.
