A dome strainer is a type of drain cover or grate that is shaped like a dome instead of lying flat across the drain opening. You’ll often see them in floor sinks, mop sinks, and large commercial drains. The raised dome shape prevents flat items like mop heads, rags, cardboard, or large food scraps from laying across the top and sealing off the drain. Water can still flow in from the sides.
In addition to dome strainers which sit lose, we offer "locking" dome strainers which prevent them from being removed, which adds protection to your drains and plumbing system.
