When installing posts, supports, shelves, doors and windows, the 3D set enables you to see both axes at a glance. And while you hold the post spirit level with one hand, you have the other hand free to make corrections and fix the unit in place - perfect!

- Whenever required, the two spirit levels linked together at right angles can be quickly separated into an 80 cm level and a handy 40 cm level.
- 2 spirit levels, Type 70 (80 cm + 40 cm):
- Light metal rectangular profile with 1 vertical vial and 1 horizontal vial.
- 2 plastic connecting brackets.
- Measurement accuracy: in the normal position: 0.029° = 0.5 mm /m.
- System accuracy: 0.057° = 1 mm /m.
