The Ratdam is a 100mm (4") stainless steel device that replaces the rod eye plug in older sewer systems, sometimes called a Broads Trap, Buchans Trap, swan-neck interceptor or just an interceptor.
Once installed into the outlet there is a stainless steel wire attached to a sliding door on the device to allow future opening and cleaning of the eye without the health and safety issues associated with personnel entering the sewer chamber to unblock the eye.
Installation is a simple matter of pushing the device into the Rod eye and drilling an 8mm hole in the chamber wall near the lid and pushing in the cable support plug to allow simple access to operate the device.
