Polylok's 1-foot tall by 20" riser has the same high quality as their 6" tall by 20" risers, but with fewer screws that you and your customers have to assemble. Structural ribs inside prevent frost from adhering to the riser in frost-prone areas.


  • Fewer screws to worry about
  • Watertight and airtight
  • Allows septic tank to be easily vacuum or water tested
  • Highest UV-Ray Protection on the market today
  • Easy to bring septic access to grade
  • Made of High-Density Polyethylene which won't shatter like some Polypropylene risers
  • Tear off the riser ring if frost is a problem
  • Same flush design to eliminate frost problems
