The Drain Strainer was invented by a former restaurant owner to protect your floor drains, wall drains and grease traps from being clogged by food solids. It also is an affordable alternative to a commercial garbage disposal. The Drain Strainer offers solid protection for your grease traps, floor drains and wall drains while still allowing the 3 compartment sinks in your bar, kitchen and dish area to drain quickly. Simply remove the stainless steel strainer drawer and either save the food debris for compost or empty it into the trash instead of allowing these solids to clog your drains.
