Installation Steps

  • Insert the wood post into the holder. Due to varying degrees of wood dryness, the edges may need to be polished.
  • Use an electric drill (not included) to drill holes on both sides, insert the gasket into the screw, and lock it into the pre-drilled holes on both sides for fixation.
  • Drill a pilot hole in the center of the wooden post using an electric drill (not included)
