Drive looped line caps onto the line posts with a mallet. Put the posts in their holes, but don’t fill the holes.
Bolt a rail cap to each brace band, tightening just enough to hold the cap in place. Feed the rails through the looped caps.
Cut rails with a pipe cutter or hacksaw, if needed. If you need longer rails, join them together. Use rails with a slightly smaller wedged end that fits into a full-size rail or with a top rail sleeve.
Be sure to deburr the ends of all cuts using a file if necessary.
Fit the rails into the rail caps. Raise or lower each cap to the final height of the mesh. Allow 2-inches of clearance at the bottom.
Tighten the brace bands to secure the rail height.
Fill the holes around the line posts with dirt and tamp until firm. Be sure to keep the posts plumb as you fill the hole in.
