Hanging a 130lb bookcase?


Hi everyone,

Hopefully this is the correct section to post in. It was either here or building and construction.


I want to hang a cube bookshelf on a wall, 18 inches from the floor.

https://www.ikea.com/us/en/catalog/products/10275862/

unit is 57inches x 57inches and 15inches deep. weighing in at 130 lbs

I spent and hour looking at various brackets at home depot last night, but other than actual shelf brackets, nothing mentioned anything about weight,

I understand it has to be mounted to studs.

Than I thought about mounting it with french cleat rated for 300lbs (one cleat on top and one on bottom)

With the french cleat though, the unit will not be flush with the wall.

I was also thinking to secure it with corner brackets ( https://www.homedepot.com/p/Everbilt...5446/202034277 ) one bracket on the left side where it would start on a stud and than 90 degree brackets on the last stud?

I'm sure i am thinking about this all wrong, and someone more experienced will be glad to correct me.

Thank you

Check on Monarch Metal Fabrication look for MF 625 Clip it is 1.5 inches in length & projection off wall is 3/16 inch.
I don't know what the load rating is.
Also they will make custom clips on request.
The company should be able to tell you how many would be needed.

Re: Hanging a 130lb bookcase?


Seeing the unit alone weigh 150 pounds (not easy to hang by oneself ) and the amount of weight a lot of books can add up to, if it were mine I would anchor it as it my sketch.

The top cross rail of a hanging book shelf should not even be factored in as a load bearing/weight supporting device. But ONLY to keep the unit from falling away FROM the wall.

Cut the 1" x 4" "ledger board (or 1" x 6" if preferred) the same width as the shelf unit overall and prime/finish coat it black. Or the wall color is desired.


Find the center of all studs, mark them with a pencil and test to be sure they will hit wood, with a small nail or 1/16" drill bit to where the bracket will cover a test hole.

Fasten the ledger board level FIRST, then set the unit on it, push it back to the wall and anchor the factory unit bracket provided on the top left of the unit. Then, add your own angle brackets wherever studs are found.


Those screws in the bottom of the unit at the back, are to be sure the unit never accidently gets pulled off the ledger board.

Good Luck on project ! ALL JMO

P.S. When installing wood screws in to studs, think about the electrical wires that may be run through them. So any screw penetrating a stud more then 1.25" is subject to unluckily hit a wire, when using Murphy's Law.

Re: Hanging a 130lb bookcase?


Greg has a great start.

But I would use a 2X as the ledger, cut as a French Cleat, with the top half screwed to the shelving, and it will be secured to the bottom by gravity, and the wedge shape.

Then the upper brackets to secure the top to the wall.

And maybe a few side L brackets to the wall, if studs are available.


The 2X can be as decorative as you want to make it, or just plain stained to match the bookcase.

Remember that a few ( lots) books get heavy quickly.

ED


I just looked at the IKEA site at this shelf, did you realize that it is rated at 29 lbs per shelf max?

That won't hold many books .

Ed, I almost drew a 2x 6 as a ledger but knowing the end of it will stick a furr piece being unsightly, so was not sure the OP would go for it. Much better it would be, but his call for sure.

Re: Hanging a 130lb bookcase?


So, I guess you want to mount it like the first picture (from the assembly instructions). The unit is intended to be supported on a flat, solid surface, not hanging (plus bracket at the top to keep it from tipping over). Make sure your support is very sold ---- shelf full of books is pretty heavy.

Re: Hanging a 130lb bookcase?


The unit is not designed to be hung on the wall. The connections are not glued, just wood dowel connected. The top and bottom are held by 4 screws, one in each corner. Everything is cheap particle board.

The unit will absolutely fail, coming apart at the seams, if you hang it on the wall. The only question is how long it will take, which will depend on how heavy you load it.

It may come apart just trying to lift it up and during attachment to the wall.

Never ask any IKEA furniture to do something it was not designed for.

Yes I would like to mount it the way Ikea says not to. The shelf unfortunately doesn't work how I need it to if it says on the floor. it also will not be used for books but little kids toys. Im going to purchase some drawers that ikea sells for this unit

I understand it is not designed to be hung on the wall, but if done properly, than why not? when I put the unit together I glued all the dowels and everywhere wood touches wood. It is pretty dam sturdy.

In order to help it not come apart at the seams even more, if I were to throw some 1000 lbs shelf brackets underneath the unit into the studs, that would hold it correct?

Re: Hanging a 130lb bookcase?


A ledger at the wall is not enough to keep this unit together. Each upright(5) will need to have a full depth bracket under it. Otherwise that front joint will fail the first time a toddler tries to use it as a ladder.

Was that particle board to particle board or was one surface colored or wood grain finish ? The finish on a lot of that stuff is essentially contact paper. While you have added to initial rigidity, how much strength you added is questionable.

Large brackets under the bottom of the unit would help. The closer they are to full length the better. You need to be careful about the weight ratings. There is at least one 1000 lb bracket advertised on the HD website that says 500 lb per pair on the instructions.

I’d still advise not trying to hang it.

Edit. Supporting it on a rigid shelf or table would be a better approach than hanging it.

Re: Hanging a 130lb bookcase?


Two times I tried posting...I'm having wifi problems today

The units we made are 36" wide X 56" tall x13" deep.

The brackets are 12" long X 12" deep and about 3" wide...
in between the brackets is a piece of wood about 3" wide...
on each end of the brackets there is an additional piece
of wood.

There is also another piece of wood running across the inside
of the cabinet at the top. That piece is also anchored to the wall.

You posted a HD link to steel corner brackets. I would make
these out of wood and paint them black-- put them
in all four corners (at least)
glue and screw them to the inside the cabinet -- that gives
you additional places to screw the cab to the wall.

The bulk of the weight will be supported by the heavy duty brackets
and the strip of wood between the brackets.

The front and sides are glass, as well as three plate glass shelves
in each cabinet. It's pretty heavy.

This is only one way to install this bookcase...I can think of another.

Re: Hanging a 130lb bookcase?


Ikea furniture may be light weight particle board and the joint hardware may not be strong enough for suspending the box. So when you put the box up, make sure you consider how well the material will hold the screws and maybe reinforcing the joints.

Re: Hanging a 130lb bookcase?


"Little kid's toys" assumes little kids will be present. I don't know anything about Ikea quality but if it is like most knock-together particle board furniture it won't hold a lot of weight - like a child trying to climb it to get a toy on an upper shelf. I don't go to their website but if it is open back, I'm not sure how something like a french cleat or two will hold it all together.
Even if it ends up being mounted on the floor as intended, I'd be anchoring to the wall.

They give you the brackets and its in the instructions, to anchor the top to the walls. IKEA's lawyers are not stupid. If they are going to sell something that may look like a ladder to a toddler, it better not hurt the kid when he tries to climb it.
