Frequently Asked Questions

Is this drain truly corrosion-resistant in saltwater environments?
Yes, forged from high-density 316 Stainless Steel, this scupper is specifically engineered for high-salinity marine environments, resisting pitting and crevice corrosion better than standard 304 steel.
Will this fit my existing 1.5-inch deck opening?
This unit features a standard 38mm (approximately 1.5") outer diameter pipe, designed for a flush, seamless fit in standard marine deck openings without the need for custom fabrication.
How does the filtration system prevent clogs?
The precision-milled filtration matrix uses a directional grid system that maximizes water flow velocity while trapping larger debris, ensuring your bilge or scupper system remains clear during heavy washdowns.
