STEP 1 - Set Posts

Map out your Horizontal Slipfence posts to be set at 75.5" to the center of each post for 6 foot wide Horizontal Slipfence Panels.

9' POST SETTING for a 6' high fence

Dig 8" diameter post holes at least 36” deep and fill the bottom with approximately 4” of gravel so that the post height is at least 76" from the ground to the top of the post.

8' POST SETTING for a 6' high fence

Dig 8" diameter post holes at least 24” deep and fill the bottom with approximately 4” of gravel so that the hole depths are at least 20" deep from the gravel the ground level.

10' POST SETTING for a 6' high fence

Dig 8" diameter post holes at least 48” deep and fill the bottom with approximately 4” of gravel so that the hole depths are at least 48" deep from the gravel the ground level.

Keep in mind the Post needs to be set 76" from the ground level to the top of the post because the Deck boards used are 5.5" wide and require 13 boards stacked for a 6' high fence and a 2" gap between the ground and the bottom board as well as a 2" gap from the top of the top board to the top of the post are both recommended.


Most areas of Canada and the USA only require a 36” hole. However, in colder climates where the frost line deepens, another 12” deeper hole may be required ie. 48” deep.

124" and 144" Posts are also available upon request.


Insert the 3” x 3” square Aluminum Fence Post into the center of the post hole ensuring that the post is at least 6’4” or (76”), above the ground level so the top of the posts will be 2" above the top of the top deck board which should be sitting 1.5" to 2" off the ground at the bottom to keep the fence boards dry.

If you are installing a 5’ high fence then dig 48” deep holes and make sure the fence posts are only 5 ‘4” above the ground level, OR Order 8’ posts from your TAHOE Slip Fence Dealer and only dig 36” holes.

If you are looking to install a higher than 6' fence, longer posts and channels are available upon request.


Pour approximately 8-10" of Post setting concrete into the post hole and then insert the post into the cements the post will end up sitting on a proper footing, then pour concrete in around the post and while the concrete is still wet, make certain that the posts are exactly 75.5" apart to the centre of each post and also try to make sure for a 6' high fence that your posts are 76" from ground level to the top of the post.

Then Level each Post on both X and Y axis. You can hold your fence posts level and in place by using stacks of the fence-boards that you will need to insert for each fence section.

DO NOT fill concrete into the post-hole and then insert post into concrete! This will make it very difficult to insert post completely through the concrete and also eliminate any repair that you may need to do later. It also may offset your posts from being exactly 76” high from the ground.

You can actually use a 6' deck board to lay on the ground as your exact space needed between posts inside to inside but leave a bout a half inch play between 6' board and posts for the thickness of the brackets.


If you run into rocks or roots or some other obstruction wile digging your post holes that may prevent you from centering the posts exactly 75.5" apart, you can always make a post section shorter or a foot longer but the manufacturer does not recommend going longer than 7' between posts unless one side of the panel is to be strapped with a center board to eliminate board warping.

NEVER make fence sections between posts longer than 8’ from the center of two fence-posts.


Repeat this same procedure to set all of the remaining posts required in your fence project.

It is imperative to set the posts in concrete and be certain to:

a) Level post both ways

b) Space the Posts apart 6 feet between posts so that a 12' deck board can be cut in half for the stack of boards in your horizontal fence panel.

c) Measure 76” to top of post from the ground level.



Make sure that Gate-post holes are the same depth and posts are set the same height above ground as the rest of your fence and approximately 48” apart (or see instructions from Gate installation guide of gate), and use all hardware provided in the slipfence gate kit and follow Gate installation instructions to set gates properly and level.


Create the gate frame first on a table or on a flat surface then attach the hinges to the gate and then hang the frame on the gate post and make sure it is level before cladding the front of the gate with wood.


If there is rain in the forecast before you are to complete your fence project, it is best to cover the hollow opening at the top of your post during construction. You can do this by placing the post-caps onto the tops of the posts temporarily (do not tap all the way on or they are very difficult to remove), so that no rain can enter the center of your fence posts during construction.


When the concrete has dried, (overnight is best), and all of the fence posts in your fence project are in place including your gate posts, place one of your deck-boards flat on the ground between your posts and shim it up to level, this provides the proper space off the ground for your first channels to be fastened to your first 2 posts.


Place the channel against the side of the post that faces the next post as close to centre of post as possible and sitting on top of the board that you had laid flat on the ground, level this channel on the post in the centre of the post then fasten to the post with stainless self drilling screws provided in the kit.

If you are on a slope and need to step the section down use a bit of the eaarth from the post hole to level up the bottom base board to level the first board.



Once the first channel is fastened to the first post ensure the board that is flat on the ground is level and this will be the seat for the channel on your next post.

Then fasten the second channel to the second post with the self-drilling screws provided and you should have two channels facing each other between two posts that are exactly level with each other.

Now Insert the “Base” board. Or bottom board. This is the first board that slips down into the channels, sits level on the flat board that was laid on the ground and screws onto the channel with 4 wood screws on both sides and each end and is the base for the stack of boards in your fence panel.  (A 6 foot high fence will take 13 boards stacked.)



If the ground is fairly level you can leave the flat board that was used to level the bottom of the channels in place and start your base-board at this level.  This will provide a 1” lift of your bottom board off the ground.



If the ground is not level and one end of you panel has a gap from the bottom of the board to the ground you can do 2 things to reduce that gap:


a) Take the earth that was dug out of the post hole and spread it along the bottom underneath the base board where the gap is.


b) Dig out some of the earth from the side of the base board that is closest to the ground until the base board is level and there is little gap underneath.


c) Shorten the space between the posts so the level step sections are shorter and the gap can be covered more easily by these two methods.


d) If there is a large gap under one side of the panel; keep the flat board laying on the ground, level your base board on top of this board and measure the gap on the wide end between the flat board laying on ground and the bottom of your base board and the length of where the base board touches the flat board. Then remove the base board and create a wedged board or boards to be fastened to the bottom of this base board using screws and glue.  Once this new base board has been created and dried insert it into the bottom as your base board again and it should now be level on top and close in the gap on the bottom.


Try to avoid racking the boards on an angle if possible as the fence looks more linear if the boards stay level.

If there is a steep hill up or down then you may need to cut the board ends on an angle to accommodate the hill and insert the boards on an angel following the grade of the property.


Install all of your base boards in your fence line before starting to stack the other boards in the panel.  This will keep the posts level in your fence project during installation and prevent them from pulling toward the finished panel.


Once the base board is secured with stainless wood screws provided, slip in three or four boards into the channels on top of the base board throughout the fence line. Securing these few boards with wood screws through the screw holes in the channels as they stack to reduce the overall weight of the full stack of boards on the bottom base board.

***IMPORTANT*** (Do not stack or finish one full panel at a time. This could pull posts toward the finished panel.) Create a low stack, for each panel in the fence line, (4 boards), then mid height, (another 4 boards), then top, (last 4 or more boards) until the desired height of you fence is met.


Once all of your Fence boards have been installed you can trim your fence posts if required to approximately 2" above the height of your fence boards to allow for a 1" post cap collar and 1" gap between the top of the fence board and the cap once installed.

Once the tops of the posts are all consistent just tap on the Tahoe Slipfence Post cap with a rubber mallet and you are DONE !

The result is a beautiful, warm, and private Wood Fence but a sturdy, long lasting, weather enduring Aluminum Fence, that was simple to install, simple to repair, and withstands all climates and seasons.




To trim aluminum fence posts you can use either a circular saw with a metal blade, or a reciprocating saw with a long metal blade long enough to go through both sides of a 3" post, or just a regular had hacksaw.
