We had just put up 3 wheelchair accessible gardens in McKinley park in Fraser, Michigan and needed drains for them to be sandwiched in-between the moisture barrier and the plywood.These fit perfect and even though we are not using the inside thread, you can thread a guided drain if needed. For our purpose as long as it drains toward the back so it does not drip on the user, we are good as is.The gasket is great but since we have the vapor barrier it has a double seal.We have had very hard rains and the underside has stayed completely dry so we are good to go. The last touch will be some type of screen to keep the dirt from migrating out and we will be in business.The only downside was two of them had burrs in the threads that I had to use my knife to clean up so the nut would start back on. I'm in the plastics industry so I understand this can happen on older mold tools. A little maintenance and they will be good agian.Very happy with them.
