Commercial kitchen sinks are prone to drain clogs, especially if the sink strainer is lost or broke. Replace your old strainer with DrainShield, a permanent locking solution for your commercial sink. Made of plastic, it is perfect for food prep sinks, 3 compartment sinks, and dishwashing sinks. It is simple to install and will fit 3.5" drain openings with existing lever drains. It prevents food particles and other debris from accumulating in drain lines and floor sinks. This is one of many drain clog solutions we offer for restaurants, commercial kitchens, grocers, and other food service providers.
