Rec. needed for tv wall mount for plaster walls


My husband and I finally found a flat screen that we liked and now we want to put it up on the walls. I figured the DIY board would be a good place for look for recommendations (moderators, please move if there is a better place for this). We would like it to be able to tilt side to side and up and down (probably not the technical terms there, can you tell I'm not the tv expert here?), support a 40", 55lb tv and be able to be used on our plaster walls.

TIA!

Why not start with the manufacture, and see what model brackets work with your TV?

For four fasteners, each one needs to support a shear load of 55/4 pounds. The tensile load in this application is probably not a problem.

Using the industry wide safety factor of four, each fastener needs an ultimate strength of 4 x (55/4) = 55# while in shear [as opposed to tension].

If the TV might fall on valuable objects or valuable people, use a safety factor of 10, so each fastener, on average, then pulls out of the wall at 10 x (55/4) = 140#.

It's not always clear on the packaging whether the fasteners are listed at ultimate strength, or there is already a safety factor (probably 4) in the listed value.

Most fasteners are rated for some thickness of drywall, and plaster is stronger, all things being equal.

Check where you bought the flat screen. they should have them or can tell you where to go. then follow the manufactures installation instructions for that bracket mount. they have done all the engineering and calculations on there product for your flat screen. With all the mounts that I have done over the years every one stated that you must secure the mount by means of a least two wall studs for a flat screen that size. I do not think you are going to find a mount that is going to swing from side to side, The mount will have to be brought off the wall some distance in order for the sides of the flat screen from not hitting the walls. You stated 40" flat screen?
Good luck BOB

I stand to be corrected! They do make a mount that swings in both direction's its called a Articulating arm. Like I said above it must stick past the wall in order for it to articulate. Thanks For the Info BIG BOB.

Thanks for the recommendations! The TV is my husband's baby so I'll pass the info onto him, I'm just looking forward to getting rid of the giant entertainment center that held our CRT.
