Designed to attach to the Hobie H-Rail to offer convenient storage on board for tackle or other small items, the 1.5 inch tray can be used or removed so that you can fit larger items inside of the box. No need to use tools to attach the H-Rail Tackle Bin, it simply clamps on to the 12-sided H-Rail. Once the box is secured to your vessel there is no need to worry about it twisting or sliding while you're trying to snag your next big trophy.
