Clicker 'Click Clack' Slotted Pop-up Waste.
The length of the body of the waste is some 75mm. The diameter of the body and threaded section at the bottom is 40mm so it fits a UK standard 'P' trap, etc. The top 'Plug' section measures 62mm across in diameter.
The centre section pushes in by hand and springs up to open. It then pushes in again to close.
The waste is solidly made from brass with a chrome finish. It comes with securing nut and rubber seals.
