BEFORE YOU BEGIN SAFETY FIRST!
Ensure that fence footings do not exceed legally established
property lines. If uncertain, refer to your real estate line plot or
consult a professional surveyor.
Check local codes for specications regarding frontage locations,
allowable fence heights, etc. A permit may be required.
Consult with local utility companies for
locations of underground cables or pipelines.
Plan, Layout & Mark
1
Locate your property’s boundary lines.
Precisely mark the fence layout – it’s the critical rst step in a
quality installation. Mark the location of each terminal post
with a stake (corner, end & gateposts are called terminal posts).
When using 8 foot 2 x 4 rails, inline posts should be spaced 97 ½"
(8 feet + 1 ½") on center, ±⁄". The exact spacing may be
modied depending on rails used, fence height and ground slope.
Place shorter sections at the corners or near gates or buildings to
make the fence t the length of the layout.

intended to provide general guidance with basic PostMaster®
fence installation. The installer must take proper safety
precautions. If you have any questions or doubts in regards
to your fence installation, please consult with a
licensed professional.
Locate & Set Posts

6' Fence / 7' 6" Post Shown
Fence Height: 74" • Post Height: 66"
Dig the terminal post holes 6" - 10" in diameter
and 30" deep. The exact diameter and depth will
be determined by local conditions.
The height of fence boards should be 8 in. above
the top of the top rail and 8 inches below the
bottom of the bottom rail with a 2 inch gap at the
bottom between the fence board and ground.
If posts are too tall after footing installation, saw
the excess PostMaster to be ush with the top of
the top rail using a hacksaw or reciprocating saw.
Center the terminal posts in the holes.
Make sure the posts are plumb, square
to the fence line and set to the correct height.
Block and support the post to preserve post
position as installation continues.
Fill the hole with concrete in a continuous pour,
mounding the top to direct water away from the post.

Make a Gate Post by fastening two
PostMaster® posts back to back with
four #12 x 1/2" gate post screws. Put
one screw in each ange, 6" below the
upper edge. Put two screws in the
anges 6" above the base of the
bottom rail.
Place the assembled gate post in its
hole, ensuring that its rail pockets will
line up with the adjacent posts when installed.
Pour concrete as with Terminal Posts.
When the terminal and gate post concrete has hardened, stretch
a string between them to set the line posts at the correct height.

POSTMASTER® INSTALLATION GUIDELINES
Install Rails
3
Once all posts are set, attach rails according to the selected fence
style. Typical fence boards are positioned 2" above ground level
and top rails installed 8" from the top of the boards. Bottom rails
are attached 8" above the board bottom and middle rails are
centered between the top and bottom rails.
Determine where to attach rails. PostMaster posts have holes, 1"
on center to make it easier to align rails at either end. For rail
adjustment references, use the pre-marked rail alignment scores
spaced 6 inch on center and starting ¼" from the top of the post.
Install Fence Boards

Nail fence boards to rails according to fence style.

SWING-IN GATE
Attach a 2 x 2 in rail pocket #1 by
fastening ve #8 x 1 ¼ inch rail
screws into it through anges
from rail pocket #3. Screws
should be evenly spaced down
the post.
Drill two ⁄ inch holes for hanger bolts in the
hat section between rail pockets #3 and #4.
The hanger bolt adjustment nuts will be
installed against the hat section.
Hanger Bolt Hole
Line Post
Attach rails to Corner Posts, using one Post Clip per rail-end.
Screw one #8 x 1 ¼" rail screw through the ange and into the
rail-end. Screw a second #8 x 1 ¼" rail screw through the ange
and semi-circular post clip hole and into the rail end.
Fasten the bottom edges of the top and middle rails to the post
clip with two more #8 x 1 ¼" rail screws.
For the bottom rail, position the post clip above rail so it can be
screwed to the rail’s top edge.
Top & Middle Rails Bottom Rails
Fasten each rail-end using three
#8 x 1 ¼" rail screws.
NOTE: If the ground slopes,be sure
to cut both rail-ends diagonally to
allow a ush t against the rail
pocket of the hat section. Post clips
may be required for fastening.
4" Cover Board
Install 6" cover boards after installing fence boards. Attach cover
board by nailing into the rail on either side of the post
