Description
The Holt Self Bailer S/S HA 4555B is a premium one-way drainage valve designed to automatically eject water from a hull once the craft is moving, while preventing ingress when stationary. Crafted with stainless-steel components for durability, this self bailer offers reliable performance in harsh conditions.
