The Leica GKNL4M fiberglass staff is a 4‑metre, three‑section, dual‑face levelling staff designed for use with Leica digital levels such as the DNA03/DNA10 and LS10/LS15.

Constructed from durable fiberglass, it provides excellent rigidity and weather resistance while remaining manageable in the field.

The staff extends from 1.6 m to 4.0 m, using three connectable sections that lock securely for stable height referencing. Both faces feature metric centimetre graduations and a Leica barcode scale, enabling precise digital readings.

A built‑in circular bubble supports quick levelling, and two integrated handles improve grip and control during setup. The staff is supplied with a transport bag, weighs 4.4 kg, and has a thermal expansion coefficient of 10 ppm/°C, ensuring reliable accuracy across varying environmental conditions.
