These robustly built dividers weigh only 3 oz. and are heftier than standard size dividers. Made in Germany of a coated marine alloy to resist corrosion. Gear synchronized arms allow one hand use and provide excellent point alignment while the center wheel / extension bar construction allows for fast action and precision adjustments.
A fine, precision tool at a very reasonable price. Easy to adjust with one hand, these dividers allow fast, precise change. Replace a point with a lead (two supplied) and you have an equally fine compass. Overall length 7".
