ᐅ How can you secure Billy shelves so they don’t fall out?

Hello everyone, I bought a Billy bookshelf from Ikea and I’m currently looking into ways to secure the shelves so they definitely won’t fall out if they are loaded more heavily or accidentally bumped. The dowels and pins provided fit reasonably well, but the shelf still wobbles slightly, and I’m worried the shelves might eventually slip out. Are there any proven methods or handy tricks to firmly fix the individual shelves without damaging the bookshelf? I’m especially interested in solutions that are as stable as possible but still reversible in case I want to rearrange the shelf later. Thanks for your tips!

Hello Germain49, your question is very specific and important for the stability of a Billy shelf. Basically, the shelves in a Billy unit are supported by small metal pins that fit into pre-drilled holes. If the shelves slip out, it is usually because the pins are not fully seated or the holes have become slightly worn.

For the most reliable solution, I recommend:

1. Check if the pins are properly inserted into the holes. They should be pushed in all the way.
2. If the holes are damaged, you can buy metal shelf support brackets that provide a sturdier fit.
3. Another option is to fix the pins in the holes with a small amount of wood glue. This is reversible if done carefully.
4. Alternatively, additional supports, such as small brackets, can be attached to the back panel of the shelf to provide extra security against the shelf slipping out.

I hope this helps you.

I fully agree! 🙂 I’ve done this myself, using small metal angle brackets under the shelf boards that are hardly visible but provide very strong support. This way, you can still move or remove the boards without permanently damaging the original perforation. Also, for a more elegant approach, you can use hook-and-loop tape to lightly secure the boards—not suitable for heavy loads, but a nice option for lighter shelving ;-)

Always push the shelves all the way down and firmly insert the pins. If they don't hold, buy new pins, either original or metal ones. Brackets work very well.

Hello Germain49,

I agree with the points made by the previous contributors and would like to add that you can use wood filler when repairing the drill holes. If the holes have become slightly widened, carefully fill them with a small drop of wood filler or wood putty, then insert the metal pins. After drying, the pins will have enough hold again.

Additionally, it is a good idea to occasionally check the fastenings of the shelves, especially if heavy items are placed on them. Billy shelves are sturdy, but depending on the load and use, they are not unlimited in capacity.

If you want to secure the shelves even more firmly, you can also attach small plywood strips to the back panel and rest the shelves on them to prevent them from slipping out. This is especially recommended if the shelves are a bit older.

Good luck optimizing your shelving!

Thanks, Laure57, the idea of using plywood strips on the back panel sounds very practical. I would be interested to know the best way to attach them—screwing or gluing? Also, do you have any tips on how to determine the position of the strips so that the shelves don’t hang too low but also cannot fall out?
