Measure distance
between posts ("x"). Mark both top and bottom rail, cut to required
length. Cut top rail 1/2" shorter than bottom rail. (*Note: Install
support leg in bottom rail every 48").
Install bottom rail in
bottom bracket attached to posts. Set top rail in post brackets. Attach
both top and bottom rails to brackets with #10 x 3/4" self tapping as
shown. Drill 3/16" holes through bottom rail every 24" for water
drainage. Level all posts and secure with remaining lag screws.

Start against one post, snap a spacer onto top and bottom
rail using rubber mallet. Insert picket and tap it tight to spacer.
Repeat until you have 3-4 pickets remaining. Install remaining pickets
as a group, spread out and snap in remaining spacers. Cut last spacer
to fit, using hacksaw. (Option) Snap first spacer in center of top
& bottom and work outwards for equal end spacing. |
