Make an incision in your board as shown above. For CAD boards - 17mm, cut a 1.2mm thick and 10mm long miter slot on each board to be joined. For U-nails - 17mm and CAD boards - 14mm, cut a 1mm thick and 10mm long miter slot on each board to be joined.
Now come and place your Joint nails as centered as possible on your future assembly
After positioning the joint nails, you can now drive them in using our pneumatic gun or a hammer.
