The Matrix 3D-R Keepnet Arm Mk2 Short is a fishing accessory made to secure a keepnet’s top rim so it stays open and stable in the water. Anglers use keepnet arms to position the keepnet near the swim without it sinking, folding over, or moving about in currents. The “Short” version sits closer to the bank and is ideal when fishing from narrow pegs or when you want the keepnet positioned low and neat beside your seat.

Built with strong, corrosion-resistant materials, the Mk2 keepnet arm gives firm support even when a net is loaded with fish. It attaches securely to banksticks, pods, or other support points and typically uses a clamp or spigot system that holds the arm rigidly. Its design allows some adjustment in height and angle so you can fine-tune how the keepnet sits in the water depending on swim depth and bank slope. The robust construction means the arm resists bending or flexing under load, which helps keep fish safe and the net accessible during weigh-ins or when removing fish.

This short keepnet arm is useful for match anglers or coarse anglers on lakes and rivers who want tidy, dependable positioning without long arms sticking out into the swim. It integrates with modular bank gear and complements other 3D-R support accessories.
