Made of marine grade 316 stainless steel, our heavy-duty boat clip is designed for saltwater use. This clip features a spring return gate that easily attaches to any point by simply pushing the clip to open the gate and a swiveling base for ease of connection. This clip is best used for temporary connections where the diver cannot see the connection point. Each boat clip is meticulously inspected at our factory to ensure smooth edges that won't cut fingers and gates open and shut reliably. Size 3-inch.
