Product Description Straightline Sumo 900 lbs:
Introducing the Straightline Sumo Sacs, the most flexible, puncture-resistant ballast bags available today. Sumo Sacs are made with a sandwiched, woven polyester core and have internally glued and taped seams for a nearly indestructible bag. The sandwich construction keeps them thin, so they are easy to fold up and store when not in use. We spent a lot of time measuring different boats to make sure that these square bags will fit anywhere on any boat.
Features:Three link valves for water and air-tight filling/draining
One traditional valve for compatibility with older pumps
Centered handle on top makes it easier to adjust the bag in compartments during filling/draining
Color coded graphics for ideal boat location recommendations.
Sumo Sac Spring-loaded link valve - creates a clean, water-tight seal that automatically opens and closes when the Uber pump is used for filling and draining, eliminating water shooting into the boat.
