Purpose and user

The New Pig PLR400 DrainBlocker Cover is a reusable urethane and vinyl drain cover designed to seal square drains up to 12 in by 12 in. It suits maintenance crews, facility managers and spill-response teams who need a quick, positive seal during wash-downs or chemical releases.

Pre-installation checks

Verify the target drain measures no larger than 12 in by 12 in so the 18 in by 18 in cover overlaps fully. Confirm the liquid temperature will not exceed 225 °F for more than 30 minutes and that ambient conditions stay between 0 °F and 120 °F during storage.

Build integration

The cover lays flat without fasteners, freeing personnel from sandbagging or temporary berms. Its positive seal contains flow instantly, while the 160 °F continuous temperature rating lets it remain in place through routine hot-water cleaning cycles. Reusable construction reduces consumable waste.

Questions about this item

Does the 18 x 18 in cover arrive alone or are extra seals or fasteners required?

The DrainBlocker cover is a single reusable urethane and vinyl mat that forms a positive seal by weight alone; no separate adhesives, clamps or gaskets are needed.

When should I pick the 18 x 18 in size instead of a larger or smaller DrainBlocker?

Choose the 18 x 18 in model when the drain opening measures up to 12 x 12 in; the cover must extend at least 3 in beyond each edge to maintain the positive seal.

What does the 225 °F liquid temperature rating mean for daily use in a workshop?

The mat can withstand accidental spills up to 225 °F for 30 minutes, but continuous service temperature is limited to 160 °F and storage must stay between 0 °F and 120 °F.
