Matrix 3D-R Cross Arm 18cm 230g 25–36mm Aluminium

Matrix 3D-R Cross Arm — Versatile Short Support for Bait Waiters and Pole Socks

The Matrix 3D-R Cross Arm in the short 18 cm version gives you a compact, rock-solid platform for bait waiters and pole socks on your seatbox, letting you keep tackle organised and within easy reach.

Quick-Release Knuckle for Fast Repositioning

The quick-release main knuckle lets you unlock, swing or remove the arm in seconds without tools, so you can adapt your setup mid-session as conditions or tactics change.

Lightweight Aluminium Construction

Matt aluminium extrusions keep weight down to just 230 g while delivering the rigidity you need to hold accessories securely, even when fully loaded.

Choose the Right Variant

Pick the length that matches your setup and how far you need to position accessories from your seatbox leg:

• Short (18 cm, 230 g) — ideal for bait waiters and pole socks close to the box; fits inside compact rod holdalls

• Medium (28 cm, 254 g) — extra reach for wider setups or multiple accessories on one leg

• Long (43 cm, 281 g) — maximum extension for pole rollers or when you need clearance around your box

All variants fit 25 mm, 30 mm and 36 mm round seatbox legs and share the same quick-release knuckle and threaded insert.
