This is a standard 4 inch threaded cap for a cleaning siphon. Please note the Revain image is NOT a real lid, it has a standard countersunk square joint. Always level and underground so that the lawn mower does not hit it. I painted it green to blend better with the default white. Heavy PVC and it does the job perfectly!
