Wall Mounting

DIY_Matt

I am going to mount an Entertainment System/TV to my wall. It is made from modular cabinets purchased at IKEA. Something VERY similar is posted as an attachment. As in the attached picture, it will be free floating and cover the majority of the wall.

The problem comes with the studs.

I want this to be flush with the adjacent wall. In order to do this, each mounting bracket will only cross one stud instead of two.

Is this a problem? Can I only have one screw to the stud and an additional two with anchors in the drywall? Is that enough support?

Depends on how heavy it is and how the weight will be distributed onto the anchors...

And with more than two fasteners no one knows how the weight will distribute.

Without knowing more I'd put a huge lag screw into the stud and test it to 4x the weight of the device to be mounted. You could then use one drywall anchor just to stabilize this load in the vertical/horiz directions.

Don't get on the Evening News.

A picture showing the suspension rail and how they connect is attached.

It also shows the suggested method of attaching to two studs. Again, the issue is if I shift the mount over it only crosses one.

Any other mounting options?

Yes. This one just percolated up from my unconscious or preconscious mind.

The steps below are not in order -
Put two lag screws through a sheet of plywood, minimum 1/2" thk, one above the other into the stud. The plywood should be slightly smaller than the outline of the TV so you can't see it in back of the TV.

Fasten the mounting rail to the plywood.

If the center of gravity of the TV and the plywood is not over the stud the lag screws will be torqued by this imbalance but they will hold.

Having installed thousands of cabinets, I can recommend both the most efficient and strongest way in this situation.
The strongest way is to remove the sheet rock and install 2x4 blocking between each stud, this is what we would insist on in a commercial application.
In a residential situation like yours, I would recommend a series of 1x3 cleats running the length of the cabinet at the cabinet anchor points usually under the top panel of each cabinet [but not limited to]
A filler or trim piece can be installed at the cabinet finished end to conceal these and make it look presentable.
For the TV I would cut a 3/4" thick piece of plywood and install this to the cabinet opening to hold the TV. This can be painted to suit the wall colour.
Anchor the flat screen TV to this.
Wall anchors are not something I would use for this application. I have learned the hard way from a cabinet becoming dislodged and falling on someone. It's better to be safeer than sorry later.........it cost my insurance company thousands of dollars in compensation.

Yep open up the wall and put in 2x6 or even larger blocking.

Usuallly this can be done so that the cabinet hides it.
