UK 4 inch Drain Inspection Cover

thingiverse

Following a recent drain clog, flooding incident I had to break my way through the inspection cover on the drain at the front of my house. I designed this replacement for the metal cover and rubber gasket because they were really hard items to find (maybe the standard has changed since the 70s when this was put in?). It fits a standard UK 4 inch rodding access and is secured with two small bolts on opposite corners. You can add some silicone sealant to the edges if you like!
