With a gradient wedge fitted between the spirit level rail and your Libella 2000, you can check inclines/gradients.

• Made from ABS plastic, which makes the wedge both light and durable.
• Gradient is measured in millimetres per metre and the gradient wedge has 20 steps between 2 and 40 mm/m.
• Simply attaches to the spirit level rail using a strong steel wing nut.

Made in Sweden
