are they bolted into the wall?

Yes but you still have to be careful about spacing and weight distribution.

It comes with 4 screws that go thru the black handle parts into the wall of the window. You will need a power tool to screw them into wood.

They are not bolted into the wall but installed with an adjustable tension rod system. They recommend bolting it into the window framework also for added security, but it is really not necessary unless you are putting some pretty heavy pots on the shelves. They include bolts also which can be screwed in thru the holes in the black side adjusters. I have had mine up for months with just using the tension mount and it fits pretty snug.

Yes, even though they are tension mounted they are also screwed into the wall.

No. Mine isn't, but they do have hardware to attach it to the wall if you want to.

Yes, they screw into place. Best (easier) to keep an existing unit on the floor and buy & stack another unit atop of the existing one - which is what I did.

I would imagine with the right screw/anchor system they could. Ours are mounted directly to studs in the wall.

Yes, they are. But the important part is to attach them strong to the wall.

Yes. They areImbedded in the manifold. Just put it in place and bolt it down.

Yes, the ends are screwed in place. The supplied hardware is not the best and depending on the wall material, may need to be replaced with higher quality fasteners.

They would have to be drilled and screws or hangers attached to the wall. I use them stacked on my CD towers.

These blocks are actually through bolted to a structure. Not screwed onto. Very different from a strength perspective. The wall has to at least as strong as plywood to support the weight.

They are bolt on. There are two holes on each end. We got them to convert our kids toddler beds because babies r us no longer carried the style we needed.

yes, easily, they are very solid and should be no problem if each unit is secured to the wall separately, they don't have a built-in mechanism otherwise to secure them on top of each other. hope that helps.

We screwed ours into the wall. I think you are supposed to screw it into the wall. We put wall anchors in for even better hold when a stud was not an option. They worked wonderfully for us!!

No. They have 2 prongs that go into slots and twist in place, they do not screw in.

Yes mine is installed in a wall. My husband made a wooden box to fit it in.

I have mine screwed into the wall. The lightbulb covers slide off and I believe the bulbs screw in.

Yes, they are. The arms screw into the base pole, there is a small section of metal, then the two arms which go a little more than half the length of the shelf on the underside.

Nope. They bolt in solid. Would be a hassle to remove. We just take our box off though.
