DrainBlocker Cover for 15 in Drains

The New Pig PLR601 DrainBlocker Cover is a square polypropylene and polyurethane mat measuring 21 in by 21 in. It creates a positive seal over storm drains up to 15 in by 15 in to stop liquid entry. The cover is designed for facility and traffic safety applications where spill containment is required.

Positive Seal Up to 225°F

The cover withstands maximum liquid temperatures of 225°F for up to 30 minutes and continuous exposure up to 160°F. Storage temperatures range from 0°F to 120°F. The single-use construction means the seal cannot be reused after deployment, so buyers needing repeated use should select a different style.

Single-Use Green Cover Only

The green cover ships as a single unit with no additional hardware, mounting clips or sealing compounds included. Installation relies on the weight and tack of the polyurethane layer to form the seal. No cleaning agents or applicators are bundled, so users must source any surface preparation materials separately.
