Hello all,

This has probably been asked many times before but the search function is not my friend today.

I have an old Panny 42” plasma that is very heavy and I wish to wall mount it. The wall is an internal one in a 1930`s house that is 6 inches thick and has a room on both sides. I have drilled a hole into this wall and it appears to be made of some form of block which was very easy to drill and didn’t really offer much restance to my masonry drill bit. My question is what fixings should I use to get the best and safest fixture of this very heavy Telly and bracket to the wall? I have a local screwfix trade counter so I can pretty much get most things from there. I was thinking these http://www.screwfix.com/prods/17480/Fixings/Frame-... or these http://www.screwfix.com/prods/12799/Fixings/Thrubo... ones. The latter make me a bit nervous as the blocks didn’t seem that strong and these seem a bit extreme and break the blocks I put them into.

Any help greatly appreciated

For the ultimate fixing use resin studs and bolts for the plasma mount. Something from here would be fine

I did consider these. Im guessing you drill the hole, brush it out and fill it with resin then slide the fixing in. Do u know how long they take to go off?

I've used the Fischer studs and resin capsules before, and they take a couple of hours to set hard enough to be able to use the stud. Very tough fixings

It does seem that technically these are very capable. In your view is it the right way to go or would the frame fixers do the job sufficiently? Incidentaly if I went with the later Id probably use 8 of them.

Coach bolts and plugs will be fine as long as you install them correctly. Studding and resin fixings are a little overkill in this situation. 10mm hole, plug, M8x150 coach bolts job done.

+1. You do not need resin and studs.

If the wall is brick, it should be in a 30's house, you may well have hit a mortar joint hence the drill going in easily. If it is block it may have been built later to divide a room? If it is Thermolite block, use a masonry bit without the hammer action on.

I did it succesfully by using 9 off 130 mm long m8 frame fixers. I drilled them at a dowwards angle and it took a lot of effort to screw in but its done. As a test I pt a 6ft level over the bracket and hung 17st off it (me)and there was no movement. Most imporstantly from a confidence point of view im convinced that its a good job and the screen is bang level too which is nice.

The 'Hang Test' is what I use, if it can take my weight it will take the TV!

I used to install plasmas back when they were 6k + - back then they were a sturdy 2 man lift, and the brackets weren't always "user friendly". IMO, the fixings above are total overkill - you'll get away with the ones you put, but if in doubt I used to use these:

Remember, the load on a plasma is a shear load - so there isn't much "pull" on the bracket to come out at the top. Ignore this if it's a daft arm bracket though.

That said, if you prefer for piece of mind use the uber fixings the posters above put - looks like vanessa feltz could do chin ups off them!

I remember a few years back I was sent out to assess a plasma that fell off the wall, the bracket had come away from the wall becuse of a poor fixing technique and the use of the wrong fixings for the wall type. The fixings where the above mentioned shield anchors, the wall type was hollow cinder blocks. Apparently the TV was installed several years ago and one side of it just fell off. It looked to me like several of the anchors had unscrewed themselves and others had opened up in to the void in the blockwork.
Im not saying the shield anchors are a bad fixing but you really do have to match your fixings to the wall and know how to install them properly.

i hate these things the problem i find is that you have to dismantle then and then use them like a screw and plug i always use coach screws and like ever has said above i always hang off the braket and also show the customer that i can hang off it ( i do this because i once had sumone ring me months after i had installed a pivoting tv saying that it had fallen off then wall when i went back to the job and reminded them the fact it helt my wait they said they then though it was ok for little timmy and his friend to hang and swing on the braket aswell ) rolleyes

Those fixings are not suitable for thermalite blocks, they will split the block. For breezeblock or any other structural blockwork they should be ok!
