Heavy-Duty 20″ Polylok Septic Tank Lid – 2-Pack

Durable & Long-Lasting Septic Tank Cover – This galvanized steel manhole cover is engineered for Polylok 20″ risers and d-boxes, ensuring a secure, leak-proof fit for your septic system. Built from high-strength carbon steel with a hot-dip galvanized finish, it resists corrosion, rust, and heavy loads—making it ideal for driveways, garages, or high-traffic areas.

The anti-slip design and glossy silver finish provide both safety and a polished look, while its reinforced structure prevents deformation under vehicle weight. Perfect for residential or light-commercial use, this 2-pack delivers reliability and ease of installation. Note: Compatible only with Polylok 20″ products—not universal for all corrugated pipe or risers.
