Plasterboard wall plugs for TV bracket

I wondered if anyone would mention "GripIt" fixings. While I agree with the engineering principles mentioned above (considering reinforcing, or fittings that grip the plasterboard) I have been quite surprised what these gripit fixings will hold.
I also agree that finding something that exactly fits the central slot is worth the time, and if you meet any resistance extending the arms then it's better to investigate why and start again then go for the brute force approach. (They make a little tool for clearing the debris / dry all adhesive that after much scepticism I bought and it did make fitting them much easier.)

Never used the Gripit fixings always thought they were an "invention" that had already been invented with a target market that was already overflowing with fixing solutions for plasterboard, I was surprised how lauded they were on Dragon's Den and that they even got an investment.
It demonstrates how good they are when the company became insolvent in 2019 and they are now manufactured under licence

Would have been a much better video if he had used a Hydrajaws to quantify the pull out strength and even then with the variables of plasterboard it would not necessarily been a conclusive test

The youtube video lacks in a lot ways and piling bricks on a shelf doesn't give any repeatable value given how the bricks were placed differently in some tests. It could be argued that the various fixings used may not have been placed to optimise their fixing strength in the test

Plasterboard is difficult thing to reliably fix to as you never know how it was stored prior to fixing, if it was damp was it dried out properly, how do you check for any manufacturing flaws in the board (yes I have found hollow spaces within boards in the past).

A TV bracket can present a number problems that need to be considered not least the leverage forces that can be present on the top fixings if the bracket has a small footprint and the TV extends significantly above the top fixings. Add to that the additional strain placed on the bracket while accessing any of the ports to add or remove or replace any additional tech while it may not be a regular occurrence it does happen

IMO direct fixing to plasterboard needs to very carefully assessed and considered especially in a customers property with TV brackets they can carry a number of sizes of TV, the customer could swap the TV you fixed for a much larger one some months down the line and the fixings may not be suited to the extra weight

We should keep things in perspective here: we're talking about hanging a TV on a wall, not building a suspension bridge.

Modern TVs are bulky, but not particularly heavy. 25 kilos for a 65 inch TV. The brackets are broad and have multiple fixing points. Put 8 fixings in them, as I linked to above, and they're solid, you could hang yourself from them. If you're fixing something huge, then the bracket will always span a stud, and you can get a couple of screws in there for good measure.

Obviously if you're trying to fit a large TV on a tiny bracket you're going to have problems with the lever effect. The secret is to not do that.

As someone who has done a number of specialist fixings courses that video is not helpful at all to anyone moving the load closer to the front edge of that shelf even by 5 - 10mm could give very different results to those demonstrated. If you are going to "publish" your experiments on youtube I think you need to be a bit more objective than just piling a load of bricks on a shelf

That youtube video is great, and is extremely useful. It's not a laboratory test for sure, but it doesn't need to be. It shows the fixings being used for exactly the sort of thing they get used for - fixing shelves, and shows the sorts of weights that might cause destruction. What more do you want?

Remove the TV from the wall-start reading more books-get a bookcase ?

Another TV bracket possibly?? 2 tvs are better than 1

fix a piece of MDF to the plaster board wall with cavity screws and gripfill and then fix the TV to the MDF.

 

[telectrix]

MDF???? I hate the stuff. Go and wash your mouth out with soap. ??

Plywood would be better, but I’m gonna plug (see what I did there) GeeFix again.

 

[telectrix]

plywood my arse. use a bit of oak or mahogany, lightly stained and french polished.
