# OX Pro 30m Chalk Reel, Aluminium, 6:1 Gear Ratio

The OX Pro 30m Chalk Reel is a refillable chalk line reel with an aluminium housing, Kevlar bold line and a stated 6:1 gear ratio. Its listed 30m capacity suits longer layout lines, while the fast rewind claim and included chalk powder are manufacturer claims rather than independently verified performance.
