Trudesign Manifold

We are fitting more and more kit in our on boats these days, such as water makers, gen sets, air conditioning etc. The engine, the galley sink and toilets all call for seawater. A single Trudesign seacock and saltwater manifold could deliver seawater to each unit meeting demand. There are advantages but there are disadvantages of installing a manifold (Sea chest) too.

Saddle Clips and Bases

These are great!

Screw or epoxy the saddle base in position. Clip on the hose grips. When you push your hose in place the grips are forced to bite down even tighter on the base.

A great design!

These can be use with cable ties adding additional security and could keep your cable runs secure and tidy
