Why Cast Iron Is Still the Standard

Composite and plastic covers have their place, but cast iron remains the default specification for any installation where load-bearing capacity is non-negotiable. Municipal roadways, parking lots, facility access points — cast iron handles the weight without cracking, warping, or settling out of position over years of service.

Our cast iron covers come from EMCO Wheaton, whose products are installed in municipalities, military bases, and industrial facilities across the country. Every cover is designed for the specific load and environmental conditions of its rated application.

Frame Options

Poly skirt — Lightweight polyethylene frame. Ideal for non-traffic areas: monitoring well access, landscaped utility areas, and residential installations where the cover won’t bear vehicle loads.

Steel skirt — Heavy-gauge steel for maximum structural integrity. Anchors into concrete or asphalt and distributes vehicle loads across the frame. This is the roadway-grade option.

Lid Configurations

• Lay-in — Standard. Lid drops into the frame for easy access. Most common for routine inspection points.
• Bolt-down — Tamper-resistant. Required for secured facilities and locations where unauthorized access is a concern.
• 3/8” lay-in — Thinner lid option for lighter-duty applications.

Available Sizes

Round covers from 6” to 24” diameter. Frame depths from 5” to 24”. If you’re replacing an existing cover, match both the opening diameter and frame depth to ensure proper fit.
