Installing a PostMaster Fence
If you are building the fence yourself or hiring a professional you will need the following items in order to create your ideal fence.
- PostMasters that are tall enough to be sunk at least 24″ below ground and reach your desired fence height.
- 2×4 Rails – 6′ fences typically use 3 rails
- Fence Boards in whatever style you like . A board at least 4″ wide is needed to fully cover the PostMaster from view.
- Corner Clips for attaching the rails at the corners.
- #8 x 1-1/4″ Truss Screws, available at most hardware stores. 6 screws for each rail.
- #8 x 3/4″ Truss Screw, Available at most hardware stores. 4 per each corner post needing to be covered.
- #12 x 1/2″ Hex Head Screws, available at most hardware stores. 4 per gate post.
- Concrete for each fence post.
- Gate Hardware: Hinges, Latches, and Drop Rods for each gate
Step 1: Plan, Layout & Mark
Locate your property’s boundary lines.
Precisely mark the fence layout – it’s the critical first step in a quality installation. Mark the location of each terminal post with a stake (corner, end, and gate posts are considered terminal posts).
When using 8′ long 2×4 rails, inline posts should be spaced 97 1/2″ (8 feet + 1 1/2″) on center, ±1/8″. The exact spacing may be modified depending on rails used, fence height, and ground slope.
Place shorter sections at the corners or near gates or buildings to make the fence fit the length of the layout.
Step 2a: Locating and Setting the Corner, End, and Gate Posts
We cannot give exact measurements on how to set your posts since each location is different. The soil conditions play a big factor in determining the depths the post need to be set. A loose, sandy soil will need more post underground than a soil that is rockier. If you are unsure of how deep to set the post contact a local fence professional.
The following instructions are for a typical 6′ fence using a 7′ 6″ PostMaster.
Dig the Corner, End, and Gate 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″ above the top of the top rail and 8″ below the bottom of the bottom rail with a 2″ gap at the bottom between the fence board and ground.
See Step 2b: Assembling Gate Posts before setting the gate posts into the holes.
Center the Corner, End, and Gate 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.
Step 2b: Assembling Gate Posts
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 flange, 6″ below the upper edge. Put two screws in the flanges 6″ above the base of the bottom rail.
Place the assembled gate posts in their post holes, making sure that their rail pockets will line up with the adjacent posts when installed. Pour concrete as with the Corner and End posts.
Step 2c: Locating and Setting Line Posts
When the terminal and gate post concrete has hardened, stretch a string between them to set the line posts at the correct height.
Dig the Line Post holes, same as the holes made for Corner, End, and Gate Posts: 6″ – 10″ in diameter and 30″ deep. The exact diameter and depth will be determined by local conditions.
Place the line posts in the hole, ensuring that its rail pockets will line up with the adjacent posts when installed. Pour concrete as with Terminal Posts.
Step 3: Installing Rails
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″ on center and starting 1/4″ from the top of the post.
Fasten each rail-end using three 8# x 1 1/4″ rail screws.
NOTE: If the ground slopes, be sure to cut both rail-ends diagonally to allow a flush fit against the rail pocket of the hat section. Post clips may be required for fastening.
Attach rails to Corner Posts, using one Post Clip per rail-end. Screw one #8 x 1 1/4″ rail screw through the flange and into the rail-end. Screw a second #8 x 1 1/4″ rail screw through the flange and the 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 1/4″ rail screws.
For the bottom rail, position the post clip above rail so it can be screwed to the rail’s top edge.
Step 4: Installing Corner Post Covers
Note: Install 4″ cover boards before installing fence boards. Position the cover board against the backside of flanges and attach with ten #8 x 3/4″ cover screws: 5 screws through each flange.
4″ Cover Board
Line up the edge of the fence board with the flange edge. Attach the fence board by fastening five #8 x 3/4″ cover screws into the fence board through the flange, followed by five more screws into the adjacent flange.
6″ Cover Board
Line up the edge of fence board with the flange edge. Attach the fence board by fastening five #8 x 3/4″ cover screws into the fence board through the flange into the rail pocket.
Step 5: Installing Fence Boards
Attach fence boards to the rails according to your desired style, using either nails or screws.
Step 6: Line, End, and Gate Cover Boards
Install 6″ cover boards after installing fence boards. Attach cover board by nailing into the rail on either side of the post.
Fasten a vertical 2 x 2 in rail pocket by nailing it through fence board. Attach cover board by nailing one side into 2 x 2 and the other side into fence rail.
Use the numbering system to identify the gate post pocket positions referenced in the following steps.
For Swing Out Gates
Attach a 2 x 2 in rail pocket #1 by fastening five #8 x 1 1/4″ rail screws into it through flanges from rail pocket #3.
Diagonally attach a 2 x 2 in rail pocket #4 by fastening five #8 x 1-1/4″ rail screws into it through flanges from rail pocket #2
Attach a 2×2 to a cover board. Install the cover board so that the 2×2 fits into rail pocket #3, and fasten the assembly in place by nailing into the 2×2 in rail pocket #4
For Swing-In Gates
Attach a 2×2 in rail pocket #1 by fastening five #8 x 1 1/4 inch rail screws into it through flanges from rail pocket #3. Screws should be evenly spaced down the post.
Drill two 5/8″ 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.
Cut a 2×2 to appropriate lengths for rail pocket #4. Attach by fastening #8 x 1-1/4″ rail screws into the 2×2 through flanges in rail pocket #2.
Cut a 2×2 to appropriate lengths for rail pocket #3 and nail to the cover board.
Install the assembly so the 2×2 fits into rail pocket #3, and fasten by nailing through cover board into the 2×2 in rail pocket #4.
Step 7: Install Gate Hardware
SWING-OUT GATE Use 8″ Ornamental strap hinge.
SWING-IN GATE Use hanger bolt with 8″ Ornamental strap hinge.
