The drawing illustrates the proper installation of in-ground vinyl posts. Two pieces of 1/2" rebar are placed in opposite corners of the post and can be held in place during installation by special rebar clips.
It is essential that this be done on every post on 7' and 8' high vinyl fences to add structural integrity to the vinyl fence. On shorter heights, only end, gate and corner posts should be set this way. Gate posts would require filling the post to the bottom of the top rail hole so the hardware will adhere better to the post. Mount the gates first before filling the gate post. There are steel inserts available by special order to substitute for filling posts with concrete. It is much cheaper to use concrete.
Make sure the rail ends are taped or plugged shut so concrete does not travel horizontally through the rail. It can add weight to the section and make it sag.
Rebar Separator Clips are designed for use in end and gate posts or any other post that needs extra support. All end and gate posts must be filled with concrete and 2 pieces of 1/2" rebar for maximum strength and performance. The Rebar Separator Clip will assure that the rebar inside the post is positioned in opposing corners of the post and is held in a vertical position.
Rebar length should extend from the bottom of the hole to:
End Posts - 1/2 way up the height of post
Gate Posts - 12" down from the top of the post
Rebar Installation Steps:
Step 1 - Attach Rebar Separator Clip to each piece of 1/2" wide rebar, approximately 12" up from the bottom.
Step 2 - Attach Rebar Separator Clip to each piece of rebar, approximately 6" down from the top.
Step 3 - Lower rebar down into post.
Step 4 - Install gate hardware (if applicable).
Step 5 - Fill post with concrete mix to completely cover rebar.
