Fernco Inc FSDP-EC Storm Drain End Cap 3 4 Inch Outlet

Product Description

The FERNCO INC FSDP-EC is a storm drain end cap designed to terminate a 39.5-inch surface water drainage channel system. It closes off the open end of a trench drain channel with grates, directing collected surface water through a bottom outlet that accommodates either 3-inch or 4-inch sewer drain pipe. The cap is constructed from a UV-inhibited material to resist sun degradation and is rated for 5-ton load capacity, making it suitable for vehicle traffic. Grates clip in without additional hardware. Lightweight construction simplifies handling and positioning during installation.

This end cap is used in residential and light commercial surface drainage applications where channel drain systems are installed to move standing or flowing water away from hardscaped and landscaped areas. Typical installations include driveways between garages, patio perimeters, swimming pool surrounds where pool water must be diverted from turf or planting beds, gardens, sport courts, and walkways. It works as part of a complete trench drain assembly using matching channel sections with grates.

Installation Notes

Installation is typically performed by a plumber or experienced drainage contractor following applicable local plumbing and grading codes. The end cap should be set into the trench bed with the bottom outlet aligned to the exit drain pipe before backfilling or setting in concrete or pavers. Verify the outlet pipe diameter matches either the 3-inch or 4-inch connection before final placement. Ensure the drainage system has positive slope toward the outlet to prevent standing water inside the channel.
