• 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

6 sizes

Available in 5, 7, 10, 12 & 15mm

On request : 3mm – ideal for fillets and slips

3 types of hardness

Available for Softwood, Hardwood or MDF

Masters AL Cassese 11mm wedges (V-nails) are designed to fit Alfamacchine & Fletcher-AMP underpinners (V-nailers). Memory shape steel & silicon coating.

Available in boxes of 8,000 wedges
