Injection-molded from UV stabilized polymers, the BlackPak Pro will last for many years, even in harsh marine environments. The ultra-stiff panels offers exceptional rigidity with minimal weight, while their interlocking joints ensure an intuitive, frustration-free assembly process. Interlocking GridLock panels utilize a tongue and groove edge design to make assembly a breeze. Just press them together and install the (included) stainless steel screws using a simple screwdriver. The water shedding lid with fully adjustable hinges allows you to go from freely pivoting to a sticky setting that maintains the lid position when you let go of it, while integrated overtravel stops keep the lid within reach and limit it to a manageable angle. Sound dampening rubber bumpers ensure quiet closing of the lid, and the unique CatchLatch retention system secures the lid in a simple but surprisingly functional manner. The included three TetherTube rod holders with integrated but easily removable hook and tether systems ensure your rods stay put if things go wrong. Caged attachment points on both sides of the tube offer multiple hook points, and the oversized hook design is sized to attach directly to the shaft of your fishing rod if desired. The TetherTube rod holder mounts to the GridLock panels, enabling several vertical positioning options. Rubber feet offer noise dampening and isolation, while Omni corner brackets enable multiple hold-down methods. They are designed as attachment points for YakAttack OmniHooks (four of which are included), generic hooks, carabiners, or simple bungee. Optimized for a wide variety of tackle boxes, including Plano 3700, Plano Edge, Bass Mafia Bait Coffin, Flambeau, and many more. The key to customizing and accessorizing the BlackPak Pro lies in the highly revolutionary GridLock 2D mounting system, which offers a plethora of attachment points on the inside and outside of the panels.
