Safely installing a TV wall bracket – but how?13. April 2018
Who doesn’t dream of a larger television? A few inches wider, an even better picture and a gigantic film experience as a result. But not every room has enough space to accommodate this, which is why flat screen devices often have to be anchored to the wall. This is an easy replacement for bulky TV units that take up a lot of space.
Televisions such as these can often weigh approximately 15 kilogrammes for a 55-inch screen, for example. Attaching this load can therefore be a big challenge. After all, safety in your own home should be the highest priority.
We’ve gathered several tips for various building materials which should be kept in mind when installing a TV. You can quickly and easily find the right fixing with just a few tricks. The subsurface and the loads that impact the TV bracket are crucial factors when selecting a plug.
The following video depicts the challenge of the load increase on the top fixing in particular when extending the TV wall bracket. This makes selecting the correct fixing even more important.
Determining the building material
The building material is crucial for determining the right fixing. If you’re unsure what building material you’re working with, carry out a test drill. The drill progress lets you determine whether you’re dealing with solid or perforated bricks. The colour of the drilling dust provides more information about the anchor base. Before doing a test drill you should first ensure that there aren’t any cables running behind the location in question, in case they are hit with the drill – this can be done with a cable detector, for example.
The drilling dust of bricks is red or yellow. If they are hollow bricks you will often drill into nothing.
White drilling dust with a sandy consistency is an indicator for sand-lime brick. The drill will often drill into space if there’s a hollow sand-lime brick.
The drilling dust is white to light grey, as fine as dust but still pourable. The anchor base is hard.
The drilling dust of porous concrete is white, coarse and slightly smudgy. The building material can also be identified by the fact that it is soft and easy to drill into.
The fischer DUOPOWR is the recommended product for all these building materials.
Gypsum plasterboard walls (drywalls):
When doing a test drill in plasterboard you will find a fine white dust that sticks to the drill.
The fischer DUOTEC is the recommended product for this subsurface. This plug offers a particularly high load-bearing capacity in this building material.
The suitable screw for the fixing
If you know your building material and the corresponding plug then the most important goal has been achieved. Now you just need the right screw. When it comes to the fischer DUOPOWER and fischer DUOTEC the correct screw diameter is given on the product. For all other fixings the following applies: the screw should be two sizes smaller than the plug. A size 6 screw should be selected for a size 8 plug.
