Installing Backing Plates

Step 4: This is the fun part. Tie both messenger lines to a steel nut. Thread the nut into an opening in the mast, and using an extra-strong neodymium magnet, drag the nut toward the mounting holes. Use a wire hook to fish each line from inside the mast. Then simply cut off the nut, but be sure to hold on to the end of the line that’s connected to the rod. The nut will either be lost down the mast or you can use the magnet to drag it back to the opening where it entered.
