Composite Access Products (CAP)™ manufactures composite covers and frames with high-speed, high pressure, compression molding. CAP covers pass the AASHTO M 306 Proof Load test requirements for American highways with the rating of HS-25. CAP is THE ONLY US composite cover manufacture to receive a state DOT approval letter for use "within roadway" zones.
CAP's traffic-rated, compression-molded, composite manhole covers are Made In The USA. If the cover does not clearly say "Made In USA" on the cover top then the cover is not American, and is most likely Chinese. If no Country of Origin is on top, the cover is violating US law-19 U.S.C. §1304(e). Where is your municipality putting US tax dollars?
CAP's composite cover and frame mate precisely with zero dimensional variation, gasketed, and bolted for optimum seal. And because CAP's do not corrode shut, this tight fit won't cause an access problem. Third-party validated by a major US utility, CAP has the "best by far" watertight cover.
CAP covers prevent iron corrosion which weakens and fuses covers shut.
Precisely mated composite covers and frames reduce pathways of water breach into system. Heavy iron covers tear gaskets easier.
Heavy Iron Covers weigh 2x-3x composite Covers. Reduce back injuries with CAP
Protect pedestrian safety and potential liability from falls into open manholes.
Transmission requires penetrating antenna with iron covers, but pass through composite covers. Antenna holes and shields are not necessary with composites.
Pigmented covers and the CAP STONE eliminate black/rusted "birth marks" in pavers
CAP eliminates the root cause of iron manhole cover theft: the scrap metal content.
Heavy iron covers reach weight limits of trucks before volume limits - thus lighter composite covers require fewer trucks.
Composites insulate pets and people unlike rapid electric/heat conductivity with iron.
