The Mast Top Plate is a classic twin track mount - if your board has two US box tracks in the 90 mm standard, this part allows you to bolt an F-ONE aluminium mast straight to the board. It’s a simple, universal setup with one big advantage: you can slide the plate in the tracks to fine-tune mast position, making it easier to dial in balance for your board and riding style.

Made from high-precision CNC-machined 6061 aluminium and fully anodized, it’s built for regular use in salt water and for riders who assemble and disassemble their setup often.
