High-quality telescopic mechanism to extend the measuring surface: the spirit level can be adjusted to the required length.
Straight edge for marking along the entire length: measure and mark
in one step, also in extended state.
Printed metric scale to determine interior measurements and hole measurements.
LOCK system for fixing the desired length in this way, accidental variation of the length of the spirit level is avoided.
Integrated anti-slip pads provide a secure hold when marking - the spirit level does not slip.
The high-quality extendable mechanism guarantees high measurement accuracy in normal position: closed ± 0.5 mm/m and extended ± 1.0 mm/m, in reverse position: closed ± 0.75 mm/m and extended ± 1.0 Hmm.
The plastic stops protect the profile in case of impacts.
