Matrix Spacer Unit 46cm 483g

Matrix Spacer Unit — Extend your seatbox height without the bulk

The Matrix Spacer Unit slots seamlessly into any Matrix Seatbox to add extra height exactly where you need it—whether that's more room for winder trays or expanded under-seat storage.

Stack and configure to suit your session

At just 3 cm tall and 483 g, each Spacer Unit delivers genuine height without weighing you down on the bank. Need more clearance? Double-stack two units to create the perfect setup for longer rigs or bulkier tackle. The modular design means you adapt your box to match the venue, the method, and the season.

Lightweight engineering for serious anglers

Matrix built this spacer to solve a real problem: seatboxes that feel cramped but weigh a tonne when you add traditional drawer units. The Spacer Unit gives you breathing room—46 cm × 31 cm of it—while keeping your rig mobile and your back happy during long match days or roving sessions.

Choose the right variant

The Spacer Unit is available in one universal size that fits all Matrix Seatboxes:

• 46 cm × 31 cm × 3 cm, 483 g — ideal for adding a single layer of height for extra winder-tray capacity or under-seat storage; can be double-stacked when greater clearance is required for deep trays or bulky gear
