Riser 500mm (20″) x 150mm (6″)

The Polylok 500mm (20″) x 150mm (6″) riser is designed for use with the Polylok 500mm covers, adapters, and the 10-hole inspection/distribution chamber. Our risers are stackable and fixed together with screws (and gaskets if needed). Structural ribs inside prevent frost from adhering to the riser in frost-prone areas.

Features:
  • Can be cast into a concrete base or tank cover if required
  • Easy to install
  • UV-Ray Protection
  • Easy to bring an access cover to grade
  • Made of High Density Polyethylene which won’t shatter like some Polypropylene risers
  • Same flush design to eliminate frost problems
