Bufftech Privacy Fence – New Lexington

1. Getting Started

• Be sure to call underground prior to digging
• Assemble gates (if necessary) and decide where they will be located
• Stake out the fence line
• Space and mark post hole locations for gate and sections (spacer bar/template may be useful)
• Start at gate end post and work outward to determine proper fence height relative to ground

2. Dig Holes

• Dig holes 30″ deep or to frost line
- hole size for 5 x 5 posts = 12″
• Clean holes and check for straight walls

3. Install First Post

• Insert post in hole
• Determine rough height
• Fill hole around post with concrete mix (sand, gravel and cement) approximately 2″ below grade
• Tamp concrete in hole to eliminate

4. Install Bottom Rail

• Tape the ends of any rail going into a post that is to be filled with concrete to prevent concrete seepage
• Insert lock ring in both ends of bottom rail
• Depress lock ring tabs, insert bottom rail in post
• Tabs will recoil to hold rail in post

5. Install Second Post

• Insert second post in hole
• Insert bottom rail in post
• Insert block under bottom rail to position of correct fence height
• Fill hole around second post with concrete mix
• Tamp, level and square fence
• Assembly may be continued by installing all bottom rails first or one section at a time

6. Support and Secure

• Level and square fence
• To lower a post, place a wood block from corner to corner
of the post and carefully tap with a mallet
• Never strike the PVC post without a wood support

7. Install Pickets and Rails

• Insert pickets in bottom rail (last picket has tongue ripped to sit flush against post)
• Insert top rail over pickets
• Depress lock ring tabs, insert top rail in post

8. Hang Gate/Install Hardware

• For complete details, see gate installation instructions in hardware box
• Note: Actual preassembled gate width for Lexington is 42-3/8″
• Position gate between posts
• Allow 1″ gap for hinge and 3/4″ for latch and gate swing
• Block up gate to square with fence; rails should be level
• Gate hardware must be mounted to two sides of the post

9. Solidify Gate Posts

• It is critical that gate hinge and latch posts are solid to ensure proper gate functionality. Two methods are available:
A. Concrete and rebar
- Use two pieces of 1/2″ rebar in each hinge, latch and
end post
- Rebar should extend from the bottom of the hole to 12″ from the top of the post
- Hold rebar in opposite corners of post with rebar separator clips
- Fill post with concrete mix to cover rebar and hardware fasteners
- Tamp post with a rubber mallet to eliminate air pockets
- Leave gate on blocks for 72 hours to allow concrete to set
B. Aluminum gate post stiffener
- Slide aluminum gate stiffener inside hinge, latch or end posts with open end facing routed hole
- Drive a screw through the vinyl into the aluminum stiffener at the bottom of the post to hold in place
- Insert post into ground
- Fill hole with concrete around outside of post

10. Install Caps

• Install post caps
• Caps may be secured with glue, silicone adhesive or #8 x 3/4″ screws, caps and washers
