Tuf-tite 24-risl-flat-sl 24 Inch Internal Safety Lid

Product Description

The TUF-TITE 24-risl-flat-sl is a 24-inch internal safety lid made from high-density polyethylene (HDPE) designed to seat inside a septic tank riser. It adds a secondary layer of protection beneath the outer riser cap, helping to restrict access to the septic tank opening. The flat profile allows it to sit flush within the riser without creating interference with the outer lid. Septic system installers and service technicians rely on this type of internal lid to meet safety requirements on residential and light commercial septic installations. At 4 pounds, it is lightweight enough for single-person handling during routine service calls.

This internal safety lid is intended for use with 24-inch septic tank risers where an internal fitting lid is required. It is suited for residential septic systems where riser lids must comply with local health department or code requirements for child-safety or tamper-resistance. The lid fits inside the riser rather than on top, making it a secondary barrier component rather than a primary cover. Installers typically pair it with a standard outer riser cap to achieve a fully sealed and secured access point.

Key Features

• HDPE construction provides corrosion resistance and long service life in underground septic environments
• Internal fit design seats inside the 24-inch riser for a secondary safety barrier
• Flat lid profile minimizes interference with outer cap installation
• Lightweight at 4 pounds for easy single-person handling during install or service
• Designed for residential and light commercial septic tank riser applications

Compatibility

Designed as an internal safety lid replacement for 24-inch septic tank risers requiring an inside-fitting secondary lid.

Installation Notes

Installation is typically performed by licensed septic system contractors or plumbers in accordance with local health department regulations and applicable plumbing codes. Before servicing any septic system component, ensure the area is properly ventilated and follow confined-space safety protocols where required. The lid should be seated fully inside the riser before the outer cap is secured. Do not use this internal lid as a standalone primary cover.
