Advantages Over Screws
  • Display deck boards to their full potential
  • Maintain even spacing, (helps air-flow)
  • No vertical fixing, so less moisture build up, (which can lead to rotting)
  • Extremely secure, even when timber shrinks or expands
  • Safer, as cannot pop out of surface
Fitting Instructions
  • Fit first row of boards with a countersunk screw. Fill the hole with a timber plug
  • Drive a fastener into exposed side of these decking boards
  • Nail fastener into joist using stainless steel nail supplied
  • Work your way along this first row of boards at chosen centres, securing Sharkstooth fasteners to the joist
  • Place second row of boards next to firmly fixed first row
  • Use a wooden block and heavy hammer to drive the boards onto exposed teeth
  • Work your way along the second row until it lies parallel to the first.
  • Install the next row of Sharkstooth on the exposed edge of the second row, on the opposite side of the joist to the previous Sharkstooth
  • Work your way across each the deck repeating these steps
Fitting With Hardwoods
For particularly dense hardwoods, such as Ipe, we recommend that a slot for the clip to is pre-routed with a 1.5mm slot cutter. This will make installation easier and prevent splitting. Set the router height so that a slot is cut at the point where the Sharkstooth will penetrate. Cut the slot to a depth of approximately 4mm, its base should be 10mm up from the base of the board. Length of slot should be approximately 30-40mm.
