SANITARY SEWER MANHOLE LIDS MADE FROM COMPOSITE MATERIAL 

Composite Manhole Frame & Cover

  • Polymer manhole lids are the best alternative to cast iron lids on highways because they have no scrap value, preventing theft.

  • ​Successfully tested to a 40,000 lb. proof load per AASHTO M-306, H-20.

  • Polymer lids are rated for traffic loads but are much lighter than cast iron alternatives, reducing injury.

  • Slip-resistant surface creates a better grip.

  • Worm gear secures lid to frame and is operated with a bronze pentagon bolt; other locking options available upon request.

  • Custom lettering on lid available upon request.
