FEATURES
The Attwood Aft-Deck Shower system (4131, 4133) is designed for
use on pleasure boats to rinse off swimmers and pets and to spray
away salt and sand. The shower systems hot and cold faucets blend
water for ideal temperature. It can also be used for cold water only.
The Deck Washdown System (4132) was designed with a high
pressure sprayer for use on sport fishing boats to wash down the rear
decks. The sprayer has a valve to regulate or shut off the water.
Both systems feature a high-styled hinged cover to store and protect
the sprayhead and controls. They are both made of high-impact,
engineering grade polycarbonate plastic.
