Compression molding is used in the production of composite coverings and frames by Composite Access Products (CAP)™.
For the best seal, the composite cover, and frame of the CAP are perfectly matched, gasketed, and bolted together. Rest assured, this close fit won’t result in an opening issue because CAPs don’t corrode or stick. CAP has the best by far impermeable cover, as determined by a significant U.S. utility.
A Note About Product Origins
It is important for local governments to know where tax money is spent. If “Made In USA” is not prominently displayed on the cover top, the cover is most likely Chinese and not American. If no nation of origin is inscribed on the top, the cover is likely against AASHTO M 306 and U.S. law (19 USC 1304(e)). Using CAP products can help ensure compliance.
