The Ultra-Inlet Guard is designed to keep dirt, sand, sediment, trash and debris out of drains. Available in several sizes and styles, the drain guard installs over the top of grates, using built-in magnets to keep it in place. Its heavy-duty material allows up to 192 gallons-per-square-foot per minute through drains, and its low-profile design can be walked on or driven over without incident. The low-maintenance guard shakes clean.
