Don’t let a gust of wind turn your umbrella into a kite. The Garbolino Multigrip Open Brolly Support is the ultimate solution for securing your umbrella to your seatbox with absolute confidence. Designed for the dedicated match angler who fishes through all four seasons, this support arm provides the rock-solid stability required to keep your gear (and yourself) dry during a downpour or shaded during a summer heatwave.
What sets this apart from standard brolly arms is the Multigrip Open System. This innovative clamping mechanism allows you to “clip” the support onto your seatbox leg at any height without needing to slide off your side trays, feeder arms, or ripple bars. It is engineered to eliminate “brolly-wobble,” ensuring that even when the wind picks up, your umbrella remains a stable shield rather than a vibrating distraction.
Open Clamp Technology: Features a high-strength hinge that opens fully, allowing for instant attachment and removal at any point on the seatbox leg.
Dual-Point Locking: The heavy-duty hand wheels provide immense clamping force, ensuring the brolly pole is gripped tightly and won’t spin or lift in the wind.
Heavy-Duty Construction: Built from reinforced alloys to handle the leverage and torque created by large 50-inch and 60-inch umbrellas.
Versatile Lengths: Available in both Short and Long versions, allowing you to customize the distance of the umbrella from your seatbox for maximum comfort and coverage.
| Feature | Specification |
| System | Multigrip Open System (Hinged Clamp) |
| Leg Compatibility | 25mm, 30mm, and 36mm (Round profiles) |
| Material | Reinforced Aluminium / High-Impact Polymer |
| Available Sizes | Short (approx. 10-15cm) and Long (approx. 25-30cm) |
| Locking Mechanism | Oversized, Ergonomic Easy-Grip Hand Wheels |
| Compatibility | Fits all standard commercial and match umbrella poles |
| Finish | Signature Garbolino Black & Blue |
Exposed Commercial Venues: Ideal for open-water pegs where there is no natural windbreak. Using this support ensures your brolly stays put when the wind whistles across the lake.
Summer Match Sessions: Use the support to position a brolly for shade. It keeps the sun off your bait and your head, preventing groundbait from drying out and keeping you focused.
Winter Rain Protection: Essential for keeping your side tray and seatbox dry. By mounting the brolly to your box rather than a bankstick, you ensure the umbrella stays perfectly positioned relative to your seat.
Concrete or Wooden Platforms: On venues where you cannot push a bankstick into the ground, a seatbox-mounted brolly support is the only way to effectively use an umbrella.
💡 Gerry’s Pro Tip
For the absolute best stability, always use two brolly supports. Mount one as low as possible on the leg and the second as high as possible. This “dual-point” contact stops the brolly pole from acting like a lever, which can sometimes twist a single clamp in high winds. It also spreads the pressure across the seatbox leg, providing a setup that is practically “bomb-proof.” If you’re using a very large brolly, try to position the supports on the leg furthest from your casting arm to give yourself maximum room to ship your pole back.
Q: Will this fit my D36 seatbox legs?
A: Yes! The Multigrip system is designed to fit 36mm legs natively and usually comes with the necessary inserts to provide a perfect, non-slip fit for 25mm and 30mm legs as well.
Q: Can I use this with a different brand of umbrella?
A: Absolutely. The internal diameter of the support is designed to accommodate all standard match umbrella poles currently on the market.
Q: Why should I choose the “Open” version over a standard brolly arm?
A: The “Open” version is all about convenience. On many modern seatboxes, you might have multiple accessories on one leg. With a standard arm, you’d have to take everything off to get the brolly arm on. With the Open system, you just snap it on wherever there is a gap.
Q: Does it come in different lengths?
A: Yes, we stock both the short and long versions. Most anglers prefer a “Long” support for the bottom and a “Short” for the top to angle the brolly slightly, or two of the same length for a perfectly vertical setup.
