The Stanley FatMax 30 metre chalk line is enclosed in a durable die-cast aluminium housing with a patented chalk view window to see exactly how much chalk is left. It contains 100ft of 50lb polyester/nylon string and will hold over 1.5 oz of chalk. A release button allows line extension without handle rotation and the line can be quickly rewound due to the 5:1 gear ratio. The specially designed hook grabs on side, top or bottom for versatility. Length: 30m (100 ft).
