Exactly what I wanted!
By SpC from 'Driftless' Wisconsin

Verified Purchase

Fitted to sailing canoe I just completed, built from a CLC kit. Otherwise auto bilge pump discharge would have had to go over deck. This way plumbing's all inside save for the tapered bronze escutcheon this fixture incorporated on the port top strake. Very elegant, very purposeful!

Bottom Line Yes, I would recommend to a friend

High Quality - Competative Price
By Steamboater from Michigan

The internal "wrench tabs" are not as large as competitors, and should be increased in size during the casting process.

Bottom Line Yes, I would recommend to a friend

Good quality fittings
By Bubba from Milford, MA

These are well made thru hull fittings. They thread easily into Groco and other brands of seacocks. It makes for a good installation.
