A plate makes it easy to install the post of a fence on a low wall. There are different models, even if the fixing method remains quite similar from one type of plate to another.

What are the conditions for installing a turntable?

Technically, the plate of a rigid fence, also called a fixing plate, is a base that accommodates the post and is fixed on a support, generally a low wall or concrete slab.

For the installation of the plate to take place perfectly, the wall in question must be at least 20 cm wide for most models. Below these dimensions, the plate will not be balanced on its support. In general, you should always use plates that are narrower than the wall. 

Furthermore, installing a plate is not recommended if you subsequently wish to position blackout panels on your rigid mesh (fence higher than 1.50m in height). The risk of being caught in the wind becomes too great in this configuration. Particularly in windy areas, the recommended solution is to install only two blackout panels (or slats) out of three to let the air pass or modify the post-installation system.

Finally, it is not recommended to place plates on bitumen. The latter deforms slightly under the effect of the sun, which can cause the plate to move and affect the stability and life of your fence. 

What types of turntables are there?

You will find several models of plates for fence posts on the market:

  •          Flat plates, which are positioned on top of the low wall;
  •          English plates, which are fixed on the side of the low wall like a wall lamp;
  •          Square or U-shaped plates, which are fixed astride the top of the wall and its side to compensate for a wall that is too narrow while ensuring the stability of the post.

There are also several types of flat plates which are the most common:

  •         plate welded to the post
  •         plate welded on iron then fixed to the post by screws
  •         sleeve plate (only for small heights)

How is the installation of the plates for rigid fence posts carried out?

First of all, you will have to choose the type of binding to use. Indeed, if the wall has cracks, is hollow, or even particularly narrow, you will have to turn to a chemical seal. In other cases, you can use expansion anchors.

Step 1: make the fixing holes.

The first step is to create the mounting holes. Draw it on your wall, respecting the dimensions of your plate. Then drill and position the dowels. It is not recommended to pre-drill all the necessary holes along your wall as a precautionary measure. Indeed, you will advance one post at a time.

Step 2: lay the plate.

Then you can put the plate in place. Depending on the model, you will have nuts or washers to secure it properly.

Step 3: position posts

The next step is to position the post in the plate (if it is not already welded to the post)

Step 4: set up the fence panel

Once the first post is in place, you can attach a rigid fence panel to it. Its fixing method will depend on the type of post chosen: with notches, clips, or collars. 

Step 5: Repeat the previous steps.

Proceed to the next deck following the same steps. And continue until your low wall fence is fully installed. 

If plates for fence posts are obvious on a low wall, it also has other advantages. Indeed, you will be able to more easily pose and install a fence with fewer efforts than in the case of the sealing of posts. It will be particularly recommended for people who install their fences alone.
