Matrix Silver Extending Leg 36mm | Ultra-Stable Seatbox Support

Stability is the foundation of every successful session on the bank. At Gerry’s Fishing, we know that a rocking seatbox isn’t just annoying—it ruins your presentation and slows down your reaction time. The Matrix Silver Extending Leg (36mm) is engineered for the serious match and coarse angler who needs a rock-solid station, even on the most challenging terrain.

Designed as a high-performance replacement or upgrade, these 36mm legs offer unrivaled rigidity. The 25mm extendable inner leg allows for massive height adjustments, ensuring you can level your box perfectly on steep reservoir banks or uneven river stones. Each leg features a large 360° rotating mud foot, which prevents sinking into soft ground and provides a solid grip on wooden platforms.

With threaded leg caps for easy accessory attachment and an ergonomic easy-grip handwheel, these legs are as functional as they are durable. Whether you are adding extra height for deep water or replacing a damaged leg, the Matrix 36mm system is the gold standard for seatbox stability.

Pro Tip from the Gerry’s Team

Take full advantage of the threaded leg caps. Instead of buying extra clamps that add weight and clutter to your setup, you can screw your rod rests, tulip grips, or even a wash-bowl directly into the top of these legs. Also, when packing away, give the 25mm inner leg a quick wipe to remove any grit or dried mud—this keeps the telescopic action smooth and prevents the inner leg from getting scratched or jammed over time.

Example of Where to Use

The Matrix Silver Extending Leg is a lifesaver in several scenarios:

• Sloping Reservoir Banks: Use the 800mm version on your front legs to reach out into deeper water while keeping your box level on a steep incline.

• River Fishing: When you need to sit “in the edge” to get your pole past marginal weed, the extra length allows you to position your box securely in the water.

• Platform Leveling: The 360° mud feet ensure a flat contact point on wooden boards, eliminating the “wobble” often found with fixed-foot legs.

Frequently Asked Questions (FAQs)

Will these legs fit other brands of seatboxes?

Yes! These will fit any seatbox that uses a standard 36mm round leg system. If your box has 36mm sockets, these Matrix legs will provide a perfect, secure fit.

Are these sold in pairs?

No, these are now supplied as single legs. This is ideal for anglers who only need to replace one damaged leg or want to mix and match lengths (e.g., two 800mm for the front and two 450mm for the back).

How strong is the locking mechanism?

Matrix uses a heavy-duty, ergonomic handwheel that provides an incredible “bite” on the inner leg. Even with the weight of a fully loaded seatbox and a large angler, the 25mm inner leg will stay exactly where you lock it without slipping.

Is the silver finish corrosion-resistant?

Absolutely. The silver anodized coating is designed to withstand the rigors of all-weather fishing. However, if you fish in brackish or saltwater, we always recommend a quick rinse with fresh water after your session to keep the finish looking brand new.
