(1) Boards Revertibility : it is recommended to position the groove at the center of the board edge. The position of the groove is given by the following formula : (H - 4mm) / 2. H is the board thickness.
Example : for a 21mm thick board : H = (21 - 4) / 2 = 8,5mm 13mm H4mm13mm 4mm * * * (H - 4mm)/2 (H - 4mm)/2 (2) The groove can not be positioned at less than 8 mm from the underside of the board. * (3) Maximum H : The position of the groove has to take into account the length of the screws used. Repeat on each joist.
Repeat step 1 to fi x the outside edge of the last board.
The hardWood Clip TM hidden fastening system allows to use plain or pregrooved deck boards. The screw head must be level with the hardWood Clip fastener.
