Clam Top Stainless Steel Scupper

Product Overview

Introducing the Cast 316 Stainless Steel Boat Scupper, a premium marine‑grade scupper drain specially designed for anchor locker drains, compartment ventilation, and efficient boat drainage solutions. Built with heavy‑duty, cast 316 stainless steel, this durable scupper withstands harsh marine environments while delivering a sleek, polished finish.

The innovative clam top design prevents ingress of water from the front, directing drainage effectively to the rear—perfect for anchor locker drainage or remote draining applications through a hose fitting. With its dual role as a vent for small compartments, this scupper enhances airflow and prevents moisture buildup, making it a versatile marine ventilation fitting.

Compatible with yachts and boats of all sizes—especially those requiring reliable deck drainage, like Fishing boats, Sailboats, and Yachts—this scupper is an essential marine hardware component for owners and OEMs alike. It's also ideal as a replacement part for clam top stainless scupper designs. Replacement Boat Parts
