Leica GTL4M Telescopic Fibreglass Levelling Staff – 4m

The Leica GTL4M is a four-section telescopic levelling staff manufactured from fibreglass and designed for use with digital and optical levelling equipment. Its fibreglass construction provides good dimensional stability during temperature changes, making it suitable for precision levelling applications.

Extending from 1.2m to 4.0m, the GTL4M features two measuring faces: a barcode scale for digital levelling and a millimetre-graduated face for conventional measurements. It is supplied with a circular bubble for alignment and a transport bag for storage and carrying.

Product Overview

The Leica GTL4M provides a versatile measuring solution for precision levelling work. Its barcode face supports digital readings with compatible Leica levels, while the reverse millimetre-graduated face allows conventional measurements. The four-section telescopic design extends to 4m, and its fibreglass construction offers greater dimensional stability during temperature variations than the aluminium GTL4C alternative.
