If your concrete tank risers are broken or cracked, the Tuf-Tite 1612-RIS 16” x 12” septic tank riser is just what you need to replace your existing risers. You can also use the Tuf-Tite riser to extend your existing concrete riser to bring it up to grade. The riser is constructed of durable HDPE material that is non-corrosive to withstand septic environments for a lifetime of worry-free service. It has an interlocking design, so it does not require the use of a sealant if used with a Tuf-Tite riser or Tuf-Tite riser lid. The Tuf-Tite 16-RISL lid must be used for a complete riser lid combination.

Note: The use of the Tuf-Tite 16TAR Tank Adapter Ring is recommended for best results when installing plastic risers on a concrete tank or riser.


  • Stainless steel screws are included.
  • Riser is constructed of durable HDPE material.
  • The risers are stackable.
  • 16” diameter x 12” high
