Wich dimensions does this have? I need the diameter of the hole needed and the parts that stick out in front and behind the hole. Thanks

Hi, this drainage valve has an internal diameter of 30mm, so it's for a 1 1/4" hole, around 33mm. The flat side of the valve sits more or less flush with the surface while the other side protrudes around 60mm. I hope that helps, best wishes and happy growing!
