CAP Broadcast on Viewpoint Project w/ Dennis Quaid!!

CAP’s composite cover technology was selected for a PBS educational broadcast. Hosted by Dennis Quaid, this high-quality production showcases the benefits with interviews from Public Works leaders from Fulton County, GA, and McAllen, TX, including how CAPs can eliminate a leading cause of water pollution.

Just CAP That!®

Composite CAPs – The Future of Manhole Covers

Composite Access Products (CAP) manufactures composite covers and frames with compression molding. Unlike other composite options (RIM/RTM/SMC), CAP’s use a unique proprietary combination of continuous/long and short fibers for both load AND surface strength. CAP covers passing the AASHTO M 306 Proof Load test requirements for American highways with the rating of HS-25. CAP is the only US manufacturer to mold in-house – rather than outsource or import – a composite manhole cover with a state DOT approval letter for use “within roadway.” And… no speed limit restriction!

US Made? Do Your Due Diligence!

CAPs are Made In The USA and proudly announce it. If “Made In USA” is not clearly on the cover top then the cover is not American -most likely Chinese. Have you audited suppliers and their suppliers-complying with the new Uyghur Forced Labor Prevention Act (UFLPA)? Complying to Build America Buy America Act (BABA)? Country of Origin laws (19 U.S. Code § 1304 (e)? Where is your municipality putting US tax dollars?

I&I causing SSOs? Use CAP’s Watertight Cover (0.00 gpm!).

CAP’s composite cover and frame mate precisely, are gasketed, and bolted for optimum seal. And because CAPs do not corrode or stick, this tight fit won’t cause an opening problem. Third-party validated by a major US utility, CAP has the “best by far” watertight cover.

CAP Manhole Covers – Innovation In Infrastructure

Corroded metal manhole cover with a dark opening, surrounded by gravel and grass, illustrating why composite FRP covers resist corrosion.

Corrosion Resistance

CAP covers prevent corrosion, which weakens and can contribute to stuck covers.

Lighter-Reducing Back Strain

CAP covers weigh approximately half traditional manhole covers. Reduce back injuries with CAP.

Data Transmission

Transmission requires antenna holes in traditional covers. Signals pass through CAPs from underneath. Holes & shields – unnecessary.

Lower Shipping Cost

Heavy covers reach weight limits of trucks before volume limits – thus lighter covers reduce shipments

CAP Cost Savings – Beyond The Price Tag

The initial price is not the true cost to municipalities. For the real cost assign a value for each CAP savings and allocate over your annual cover purchases.

Hidden Costs of Traditional Covers

  • Frequent Lid Replacement Contractor Costs
  • Replacement Sewer Cover prices after Theft
  • High-cost special coatings for Corrosion Resistance
  • Rain Guard leak capture products
  • Excess electric bills from overworked lift station pumps due to added rain water inflow
  • Fees from SSO EPA penalties
  • Insurance Premiums For Citizen Injury Lawsuits
  • Legal Fees
  • Public Relations Shame and Embarrassment
  • Traffic Back-ups
  • Tack Welding
  • Workman’s Compensation Claims for Back Injuries from Lifting Heavy Sewer Lids, Finger Injuries from Sharp Iron Edges
  • Eye contusions and skin lacerations from rocks jumping off of covers when slamming with a sledgehammer
  • Disability Costs, ER Visits
  • Investment in Specialized Sewer Cap Lifting Tools
  • Overtime for Inefficient Worker Productivity
  • Longer Installation
  • Employee Morale and Turnover
