My daughter has asked me to fix a Vogels wall mount bracket in her lounge
and then attach her Sony 40" LCD box to the bracket.
No problem but I am somewhat concerned about the fixings supplied.
The wall is double skin brick/cavity/block. The blocks are very soft,
Thermalite or similar I think, and 100mm thick.
The fixings supplied are plastic plugs with 8mm screws, 80mm long. These
fixings seem to be of decent quality.
The fixing centres for the bracket are approx 220mm horizontally x 100mm
vertical.
The bracket has a single arm that allows the box to swing out up to 90
degrees from the wall.
The tv box weighs about 30kgs
I'm a bit worried that the weight of the box on the arm will be more than
the 4 fixings can support.
This is not the sort of thing where you get a second chance !

I was wondering about either more substantial fixings but wouldn't know what
to go for (I suppose shield bolts might be an idea), longer screws/plugs
like frame fixings or fixing timber to the wall an attaching the bracket but
this is the least preferred option.

Any thoughts or ideas please?

Nick.

Have you checked the model of bracket she's got is suitable for the
size/weight of the TV?

How about resin fixings?

Haven't used them myself yet, but they often seem to be recommended for
fixing to loose or weak materials.

I think you are right to be concerned. 30kgs isn't too bad on its own, but
if it swings out the diagonal force on the fixing will be huge & if the
blocks are soft they will either come out or could break away.

I'd suggest a fixing kit that doesn't swing if thats possible - and one with
multiple fixing holes. I've fixed TV's to plasterboard walls before now by
using 10 or 12 hollow wall anchors, but the bracket has been around 50cm x
10cm with about 20 holes in two rows.

Thanks Dave,

I've never heard of hollow wall anchors but will google.
It will be possible to drill the bracket to take more fixings, but I fear
nothing like 10 or 12.
Unfortunately a fixing kit that doesn't swing is a non-runner because of the
location.

Thanks for your help,

Nick.

I had a fixing with a swivel arm that was supposed to be good for up to
40" TVs a lot heavier than our 32" Sony. Our block wall held but the arm
flexed horribly. The bottom end of the mount has a good 1/8" of packing
between it and the wall to balance off the current 28" TV.

As has been said a bracket holding the TV parallel to and close to the
wall will exert a lot less leverage on the fixings.

One option would be to fix a larger "plate" to the wall first - say
3/4" ply or MDF, and then screw the mount to that. That way you can
spread the load and give the fixings more mechanical advantage to
counteract the leverage of the bracket. You could also use extra
fixings on the plate - say 4 along the top and a couple at the bottom.

A use a liberal amount of Gripfil?

Persuade her that wall mounted TVs are for Chavs only.

Yes, there is a problem there I think. I got round it by removing
three thermalite blocks and cementing in concrete blocks. The other
alternative is to fix a large piece of thick ply with multiple fixings
and then fix your bracket to that.
There are specialist fixings for soft blocks but I personally wouldn't
trust them for this. As well as the weight of theTV, people can lean
or pull on it. Lotta dough hung on the wall there.

Yeah, 30kg on the end of a 15 to 20 inch arm has a lot of leverage.
The top fixings will be being pulled fairly hard not something many
are designed to withstand, shear yes tension no.

Judging by the adverts, insurance companies are finding that out the
hard way...
