Rectangular Inlet Frames & Grates

Current US Foundry square and rectangular inlet frame-and-grate combinations. Every listing is an exact catalog number in the manufacturer's current Inlet Frames & Grates search category. Dimensions, material, and load labels come only from that exact current record; historical frame-style, DOT, flow-area, and proof-load claims are not carried into the release. All products are quote-only, and Drainage Connect confirms fit, configuration, and current availability for the project.
