- THE original wedge (V-nail) invented by Cassese in 1976, now designed for your underpinner (V-nailer)
- 11mm wide to fit Alfamacchine or Fletcher-AMP underpinners (V-nailer)
- Very high tightening power thanks to unique shape memory steel alloy
- Color coded silicon to recognize type & hardness easily
- Unique silicon coating to prevent jammings and ease stacking
Shape memory steel
Wedges are made from a special steel alloy which gives shape memory properties to the wedge.
This way, when it penetrates into the moulding, it spreads its wings which – because of shape memory- try then to come back to their initial position
State-of-the-art sharpening
Each wedge is controlled by laser to ensure a perfect regularity & maximum efficiency
Silicone coated
Wedges are not stuck together with glue or adhesive, since the accumulation of their residue can create jamming in the firing mechanism.
The silicone spreads along the wedge, and thus helps it slide and insert much better into the moulding
Color Coded
In order to identify quickly the wedges inside or outside the underpinner, silicone is colored depending on the hardness of wedges :
- Grey silicone for AL Softwood
- Black silicone for AL Hardwood & MDF
