Fernco Inc FSDP-QUAD 4-way Storm Drain Corner

Product Description

The FERNCO INC FSDP-QUAD is a 4-way storm drain corner fitting designed for use with grated drain channel systems. It serves as a directional junction piece that connects four sections of drain channel at a single corner point, directing collected surface water toward a bottom outlet. The bottom outlet accommodates 3-inch or 4-inch sewer drain pipe, allowing integration with standard below-grade drainage piping. Grates clip directly into the channel without additional fasteners, simplifying assembly. Plumbers and drainage contractors install this fitting as part of a complete surface water drainage system on residential or commercial properties.

This fitting is suited for surface water drainage applications where channel runs meet at a corner or four-way intersection. Typical installations include driveway aprons, parking areas, pool decks, patio perimeters, and other hardscaped surfaces where controlled stormwater runoff is required. The unit is sold individually and integrates with compatible drain channel and grate components. The channel surface dimension is 39.5 inches along the A measurement. The clip-in grate system reduces installation time compared to fastener-based designs.

Installation Notes

Installation is typically performed by a licensed plumber or drainage contractor. Shut off or divert any active water flow to the work area before beginning assembly. Ensure the bottom outlet connection to the sewer drain pipe is properly sealed per local plumbing code requirements, which may reference IPC standards. Do not force-fit channel sections; verify channel alignment before clipping in grates to avoid stress on the fitting body.
