The Tuf-Tite 12-inch domed green lid is a durable, high-density polyethylene cover designed to provide secure, weather-resistant access to septic tanks and other underground systems. 

Features:

Material: Constructed from high-strength, injection-molded HDPE (high-density polyethylene) for long-term durability.

Design: Features a domed top that effectively sheds water and debris, preventing pooling on the lid.

Seal: Includes a molded-in polyurethane gasket to ensure a watertight and secure seal every time, eliminating the need for O-rings.

Security: Comes with stainless steel safety screws for a secure and tamper-resistant fastening system.

Compatibility: Designed to fit specifically with Tuf-Tite 12-inch diameter risers and adapter rings (models TT-12-RIS and TT-12X12-RIS).

UV Resistance: The polymer construction is UV-resistant for an extended service life in outdoor applications.

Safety Feature: The lid has inner rings designed to hold up to 64 lbs of concrete for added safety and weight if desired.
