To fit sink bowl sizes between 580-610mm in length and 430-460mm in width. Standpipe not included. IMPORTANT NOTES: The Mechline food waste strainer comes ready assembled for a right-hand side drain waste. If the system is to be fitted in a sink bowl with the drain waste located on the left-hand side, the cover plates are very easy to swap over. For the food waste strainer system to work efficiently, a plug upstand strainer is required. The upstand must be lower than the sinks brim.
