Our Most Popular Dividers 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 centre wheel/extension bar construction allows for fast action and precision adjustments. The Weems & Plath Ultralight features hardened stainless steel points and is fully adjustable. Replace a point with lead (supplied), and it becomes a navigator's compass. Length 7".
