Stanley 0-42-287 Aluminium Line Level 80 mm

The Stanley 0-42-287 is an 80 mm aluminium line level, a small single-vial level that hooks onto a string line. Special hooks let it slide freely along the line, and a flat bottom lets you use it on a surface too. Its lightweight metal body is built for long life, and the yellow vial uses high-visibility tinted liquid for clear readings. Stanley rates accuracy at 2 mm/m and says it suits setting out levels over large areas where precision is secondary, such as landscape gardening.
