The Matrix 3D‑R Keepnet Arm Long is a fishing accessory designed to securely support a keepnet so it stays open and stable in the water while you fish. It attaches to banksticks, pods, or other support systems and holds the top rim of the keepnet at the desired height and depth. The longer version gives extra reach compared with shorter arms, making it useful when fishing from wider pegs or deeper banks, or when you want the keepnet positioned further out from your seat.

The arm is constructed from robust, corrosion‑resistant materials that stand up to repeated use in wet conditions and resist bending under load. The design allows some adjustment in angle and height so you can fine‑tune how the keepnet sits, helping prevent it from collapsing, shifting in currents, or resting awkwardly. A stable keepnet support is important for keeping fish safe and easily accessible during weigh‑ins or when removing them from the net. The longer reach also helps position the keepnet clear of your feet and gear, reducing the chance of tangles or damage. Overall, this arm enhances control and organisation of your keepnet setup and integrates well with modular bank gear systems.
