Product advantages
Work productively
- Short forming times due to ready-to-use elements available in 2 different widths and 3 heights
- 30 m² transferable via crane with no additional bracing
- Low transport volumes and great stackability as a result of the minimum element thickness of only 21 cm
- Easy height extensions with the MANTO aligning panel clamp
- Inner and outer elements available in various heights
- Additional edge protection of the formwork facing with MANTO edge profiles on the outside
Work safely
- Millimeter-precise radius adjustment using turnbuckles and fine-tune alignment thanks to lever edge on profiles
- Height extensions can be made using the aligning panel clamp from MANTO
- The element connector is easy to use and allows timber adjustments of up to 15 cm
- Easy turnbuckle operation using an open-ended spanner or tie rod (< Ø18 mm)
