Shop by Material
- Cast Iron — Load-bearing covers for roadways and vehicle-traffic areas. Lay-in, bolt-down, and monitoring configurations. The default for any installation that sees vehicles.
- Composite — UV-stable, corrosion-resistant covers for coastal, chemical, and industrial environments. Up to 70% lighter than cast iron. Won’t rust or degrade in sunlight.
- Steel — Heavy-gauge steel-skirt frames for maximum structural integrity under traffic loads. Anchors into concrete and asphalt.
Common Applications
EMCO Wheaton covers are specified for sewer access points, water utility manholes, monitoring well surface completions, stormwater infrastructure, and industrial vault access. The right cover depends on the load environment (foot traffic vs. vehicles), exposure conditions (coastal, chemical, UV), and access frequency.

FAQ
Is EMCO Wheaton the same as EMCO Industries?
EMCO Wheaton is the brand name for the underground access product line. Their manhole covers and frames are manufactured specifically for sewer, water utility, and monitoring well applications.
Can I get just a replacement lid without the frame?
For composite covers, yes — we carry lid-only options in most sizes. For cast iron, the lid and frame are typically sold together, but call us to confirm availability for your specific size.
Do you carry EMCO Wheaton’s full product line?
We carry their full range of manhole covers and frames — cast iron, composite, and steel in round and square configurations. If you don’t see a specific EMCO Wheaton item on the site, call (866) 514-3684 and we can source it.
