UK 4 inch Drain Inspection Cover

thingiverse

Following a recent drain clog, flooding incident I was forced to smash my way through the inspection cover on the drain at the front of my house. I engineered this replacement for the metal cover and rubber gasket because they were extremely hard items to find (possibly the standard has changed since the 70s when this was installed?). 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 desired!
