Gradients, angle scales and the trades that need them
Both PRESCH products on this site do something adjacent to the obvious job.
Specializing. The 40 cm (15.7 in) level carries a curved horizontal vial with 2% gradient control — the fall that paving and terraces are laid to — and a vertical-view window for reading a vertical from the side. The 3 m (10 ft) folding rule carries an angle scale in its joints, so it marks angles as well as lengths.
Base specifications. The level publishes no accuracy in millimeters per meter, where the Bosch and Stabila in the same hub publish 0.5. For general leveling that is a real gap.
The level, if you lay anything that has to shed water. The gradient vial does in a glance what a level and a packing piece do in a minute.
3 m (10 ft) beech · EC class III · integrated angle scale
A 3 m (10 ft) beech rule with an angle scale printed into the joints, so it marks and sets angles as well as lengths — the one function a plain rule cannot do at all.
Best for: Roofing, joinery and anything where the question is what angle, not just how long.
40 cm (15.7 in) · curved horizontal vial with 2% gradient · vertical-view window
A 40 cm (15.7 in) level specified for gradients rather than for level: a curved horizontal vial with 2% fall control, plus a vertical vial with a viewing window for reading verticals from the side.
Best for: Paving, terraces and anything that has to run away from a building rather than sit level.
