Product Details and Uses

Preston Innovations Offbox36 Keepnet Arms

In high-stakes commercial match fishing or competitive natural venue leagues, every second saved translates directly to more fish in the net. Fumbling with awkward, traditional screw-thread attachments at the end of a exhausting five-hour matching session does more than kill your rhythm—it risks damaging your gear and slowing down the weigh-in officials. The Preston Innovations Offbox36 Keepnet Arms represent the next generation of seatbox accessory design, delivering a highly advanced, ultra-reliable mechanical solution that makes keepnet management completely effortless.

As a signature component of Preston’s industry-leading Offbox36 ecosystem, these arms are built around the revolutionary Snap-Lok quick-release system. Instead of continuously screwing your keepnets directly into a rigid bracket on the bank, the Snap-Lok design allows you to leave the threaded insert permanently attached to your net block. When you arrive at your peg, you simply click the net into the arm housing; at the end of the match, a quick press of the release button pops the net free instantly, letting you slide your catch into the weigh-tripod with ultimate efficiency.

At Gerry’s Fishing, we appreciate hardware that eliminates common bankside headaches. Preston has completely overhauled the framework of these arms, packing them with ergonomic anti-snag wheel nuts and captive internal inserts to ensure maximum stability and zero line damage throughout your session.

Key Features & Construction

  • Snap-Lok Quick-Release Innovation: Features a heavy-duty, spring-assisted locking chamber. Once the threaded block is clicked into the arm, it establishes an iron-clad connection that will not budge under the weight of a heavy catch, yet releases instantly with a single push of a button.

  • 360-Degree Rotational Adjustability: The open-knuckle clamp design allows the arm to be rotated smoothly into any vertical or horizontal angle before locking down. This gives you total control over how your nets sit in relation to your footplate and seatbox setup.

  • Anti-Snag Ergonomic Hand Wheels: Preston has completely radiused and smoothed down the structural adjustment dials. This streamlined profile completely removes sharp catch-points, ensuring your fine monofilament mainlines or loose pole rigs never wrap around the wheel during high-speed fishing.

  • Captive Internal Insert Design: Unlike older generations of accessory arms where the plastic reduction collars could easily fall out and get lost in the mud or water, these inserts lock securely inside the knuckle frame for stress-free bankside modification.

  • Indestructible Polymer Blend: Built to comfortably withstand the brutal twisting leverage exerted by multiple large commercial keepnets packed with heavy bags of carp and F1s.


Where to Use: Recommended Scenarios

  • High-Volume Commercial Match Packing (Short Version): The Short arm is the definitive choice for match anglers utilizing modern footplate configurations or multi-net accessory bars. It keeps your keepnets clamped incredibly tight and flush to your platform, establishing a hyper-efficient “dropping zone” that maximizes your pole handling speeds.

  • Steep Natural Banks & Rivers (Long Version): The Long arm is specifically optimized for scenarios where you are not using a footplate, or when setting up on high, uneven natural banks. The added length projects the keepnet body well clear of your seatbox structure, ensuring the mouth of the net rests safely in deep enough water to preserve fish welfare.

  • Frantic Weigh-In Transitions: Eliminates the stress of the match conclusion. When the scales arrive at your peg, you can detach three or four individual nets in a matter of seconds without twisting the mesh or fighting stuck threads.


The Gerry’s Fishing Verdict

The Preston Innovations Offbox36 Keepnet Arms are an absolute triumph in modern match tackle ergonomics. Preston has taken a historically frustrating task—screwing down wet, heavy keepnets—and turned it into a seamless, click-and-play process. The integration of the anti-snag hand wheels is brilliant for pole anglers who frequently drop line near their legs, and the raw stability on a 36mm leg is completely unyielding. For any angler running a modern seatbox station, these arms are a mandatory investment to streamline your workflow.

Gerry’s Pro Tip: To build the absolute ultimate commercial multi-net array, try utilizing a combination of both Short and Long arms on your front footplate legs. Mount your primary silverfish or F1 net to a Short arm on the inside leg to keep it right under your hand for maximum speed. Then, clamp a Long arm slightly further down the same leg to angle your dedicated big-carp net outward at a 45-degree angle. This clever stepping configuration keeps both nets fully open and easily accessible, while completely preventing them from overlapping or crushing together in the margin!


Frequently Asked Questions (FAQs)

Will these arms fit other brands of seatboxes like Daiwa, Matrix, or MAP?

Yes, absolutely. While natively bored out to fit modern heavy-duty 36mm round legs, every factory pack comes complete with a full suite of captive reducing inserts. This allows the arms to lock with absolute, non-slip precision onto 30mm round, 25mm round, and 23mm square box systems, covering almost every modern chassis on the market.

Can I purchase extra Snap-Lok inserts separately if I have multiple nets?

Yes. Preston sells the Offbox Snap-Lok Accessory Inserts independently in handy multi-packs. This allows you to fit the threaded blocks permanently to all your commercial carp, silverfish, and river nets, allowing you to cycle through any combination of nets using the exact same keepnet arms.

Which size should I buy if I always fish with a standard footplate?

If you routinely set up with a front footplate attached to your seatbox, the Short version is highly recommended. The short length brings the mouth of the keepnet directly to the front corner edge of your platform, minimizing the distance your arms have to travel to drop a fish, which dramatically boosts your catching speed during a frantic bagging session.
