Hey folks,

A friend of mine asked me to build him a small shelf to allow his television to slide in and out from its current location. What he’s looking for is along the lines of this:

I don’t think he is necessarily opposed to buying one, but that would look a little too commercial-ly for his setting, and wouldn’t match at all. Plus, if I could save him a few bucks in the process and get some shop time out of it, then it’s a win-win.

My question boils down to this: Initially I was considering grabbing some 100 lbs drawer slides, like these, and basically building L-brackets out of plywood, to mount the slides to top of the cabinet the TV is currently on and a plywood shelf with protruding rails below to attach to the slides. I hope that makes sense…

As I thought more about it, I got to wondering whether or not the wood would last over time and whether the slides would be ridged enough to support a TV (the TV weighs no more than 60 lbs), so I am now considering mounting the slides to steel angle, and building the shelf off that with basically a wooden case to conceal the mess of steel. I have no doubt that the steel angle will hold up over time, but my concern that the slides would have side-to-side play remains.

Do any of you have experience with something like this? I’ve never really tried taxing drawer slides in this manner.

I have done this with Acuride 7900 series heavy Duty slides.
They can support 350lbs mounted vertical on the sides of drawers, but you can lay them down flat also.
In the flat orientation they are still rated for 150lbs
A pair of 16” slides sells for ~$64. About a dollar per inch more for longer.
Laid flat they are 3/4” tall and I put a pair between two shelves of 3/4” plywood. Like this, as long as the mounting gap is below eye level you don’t even see the mechanicals at all. Just looks like a floating shelf.

Here is an image of the slide I’m talking about.

Have your say...
