Perko Garboard Drain Plus w/Steel Wrench

The Perko Garboard Drain Plus with Steel Wrench is a purpose-built through-hull drain assembly engineered for marine applications where reliable bilge and deck drainage is essential. Constructed from cast bronze with a brass plug, this garboard drain combines corrosion-resistant materials with a complete installation and maintenance package that includes a zinc-plated steel wrench.

Key specifications reflect serious marine-grade construction: the cast bronze flange features a 3-1/8" outer diameter and accommodates 1" pipe with 1" of threaded engagement. The #10 screw fastening system ensures secure deck mounting without requiring additional hardware. The brass plug provides corrosion resistance in saltwater environments where standard steel would fail rapidly. The zinc-plated steel wrench—included in this Plus package—enables straightforward plug removal for cleaning and maintenance, reducing downtime and extending the drain's operational life in harsh marine conditions.

This drain assembly serves recreational boaters, commercial vessel operators, and marine maintenance professionals who require dependable through-hull fittings. Proper bilge drainage is critical for vessel integrity; a compromised garboard drain can lead to water accumulation that threatens stability and promotes structural deterioration. The Perko design handles both routine drainage and emergency pumping scenarios common in offshore and coastal operations.

Perko has established itself as a trusted manufacturer of marine hardware, and this garboard drain reflects their focus on corrosion-resistant materials and field-proven engineering. The included wrench eliminates the need for improvised tools, reducing the risk of damage to the plug or surrounding deck hardware during service cycles.
