I have an awkward spot to hang a 50” Samsung UA50MU6100 it has 40cm centres on the back.

Tv needs to tilt down and side to side, plus lower and higher. The wall is timber but...there is a beam that sticks out 30cm from the wall and has a 4cm facing either side over a steel plate. The TV needs to be centred in front of the beam. Its presently on a stand which means a bulky unit underneath.

What type of bracket do I need, and where is the best place to fix it. The beam looking at it front on, is
17cm wide and includes the two 4 cm boards either side. Can it be attached to the back wall and safely come out over 40 cm to clear the beam? Is fastening on the beam a better option?

Any suggestions appreciated.

I'm guessing anything fastened directly to the beam will be a no-go, as it appears to be a structural element?

 

If that is the case, you could look at an offset mount fastened on the wall behind that can articulate out far enough to put the TV in position square in front of the beam, something like this maybe?

 

It may sag over time, but it should work.

Looks like a Lockwood , n'est-ce pas ?

 

What is the thickness of the wall ?...

 

The doc below indicates its likely to be 44 or 62mm? , if its 44mm it might require some packing is the arm mount needs long screws...

Did you say the beam is steel with a wood around it to hide it? if so, drill and tap the steel. you could get away with a bracket with quite a narrow wall mount.

Yes it's a Lockwood, an old one with much thicker walls than those specs. Closer to 10cm thick as its an exterior wall. I could safely go quite deep.

Yes the beam is wooden on the face so you can drill in from the front, but through the sides would hit a plate.

Have to pick up the car from garage now so no time. Will comment later, but thanks for any thoughts. Am a bit baffled by all the different types.

Looking at it again, the beam is the right place for the bracket to go on so as to centre the TV in the room otherwise it will be too close to a window.

I could pack the 85mm recess in the beam to accommodate the suggested bracket. Funny how when you write a question down, the answer soon becomes clearer. Many thanks.

If you are mounting on the beam this won't be an issue but the exterior wall is a sandwich of timber and foam insulation. You would probably only be able to count on the inside layer of timber (~40mm?) to hold screws.

The old original Lockwoods did not have an insulation layer like the newer versions. The walls are amazingly thick I used to have a leftover piece of outer wall where you could see the solid cross section. The idea then was that the walls were so thick they were self insulating like a log cabin. Its just difficult that the beams are everywhere and you need to consider them for any placement. It didn't occur to me when I asked that I could pack out the front of the beam and so was not as limited to bracket base size after all. Many thanks.

The physical job of getting the TV and bracket on there are now going to be the challenge. Everything looks easy until you start.

Just take your time, measure three times, and get a hand to move the TV on to the bracket.

 

I have two similar if not the same as this: https://www.pbtech.co.nz/product/MOAOMP7436/OMP-CANTILEVER-TWIN-ARM-TV-WALL-MOUNT-XLARGE-42-70

 

You could fit the bracket to the wall and extend the mounting face outwards so that the TV sits in front of the column. I used 40mm screws I think, and probably 6-8 of them into a much thinner wall than you have.

I have a bracket similar to pbtech's Loctek 26"-55" PSW831A on a 42" LG. The bracket is rated for 25kg which is twice the weight of a Samsung 50" and it lends itself better to a narrow mounting.

Thanks, will look at all the suggested ones. I think youtube will help a lot too. Am very lucky to have a solid wood to screw into, it makes everything much easier.

Get a piece of 18mm plywood cut to the size of the wall plate of your selected cantilever bracket.

 

Screw that to the face of the 2 40mm timbers projecting from the wall, then fix the cantilever bracket to the plywood with 4 6mm bolts (one each corner)

 

Alternatively, ask a sheet metal worker to cut you a piece of 3mm sheet steel and use it the same. (spray can it black to match and you will have a real professional looking job!)
Your tv only weighs about 12kg

It doesn't have to be on the outer face of the beam. Something filling the recess could be extended down to conceal various cables going to the tv and stained to match.

All your suggestions have woken me up to the fact that cables will be hanging down in full view whereas the cabinet hid them before. Now not only do I need a bracket, I need the method to hide the cables. Would have to be a nice piece of wood that would varnish up to match. It would also need to be able to be removed easily rather than unscrewed each time.

Sigh..Experience is something you don't get until just after you need it.

Or just a cavity open top and bottom. Over a metre or so and with gravity helping you can likely just push them though.

 

 

 

I don't think you need to pack the space between the edges of the beams. The forces on the bracket are concentrated at the edges; more screws or backing in the middle will do almost nothing.
