ᐅ Kallax connector parts don’t hold – is this a known issue?

Hello everyone,

Lately, I have noticed that the connecting parts of my Kallax shelf, like the small clips and connectors, simply do not hold properly. They often slip out or are not tight enough, which makes the entire shelf feel wobbly. I have made sure to assemble the connections according to the instructions.

I wonder if this issue with the connectors is generally known, or if I might be doing something wrong? It mainly concerns the elongated connectors that are supposed to hold the panels together.

Has anyone else experienced something similar? Are there replacement parts or modifications that could solve this problem? I would also be interested in tips on tools or techniques that could sustainably improve the stability.

Thank you in advance for your insights!

I know that. Just remove the connecting parts again, apply a little wood glue or glass adhesive at the joints, and then the parts will fit better.

That sounds frustrating when the parts don’t hold properly. I once had a similar Kallax shelf; the connections held up well for me, but I was always careful during assembly. It might be due to the quality of the clips, as some batches seem to be less durable. You’re not alone with this issue!

Hello Bapeo31,

I can completely understand your issue. The connecting parts in Kallax are not designed to be particularly robust, which is also due to the shelf’s construction, as it is intended for moderate loads. If the connectors don’t fit tightly, this could have several causes:

1. Slight manufacturing tolerances at docking points or connectors
2. Wear from repeated assembly and disassembly
3. Possibly incorrect positioning or twisting of the clips when inserting them

I recommend first checking that the parts are positioned correctly, as some connectors need to be aligned properly when inserted. If they still don’t hold, applying a thin felt pad on the contact surfaces can often help to make the mechanism a bit tighter.

Ikea sometimes offers replacement parts, which I have experienced myself.

Have you considered repeated assembly or moving as a possible cause?

The Kallax components are made of MDF with a coating, which can lead to a loss of strength around the drill holes after repeated assembly. The connectors, especially the small clips, engage in grooves and holes, where dimensional accuracy is crucial for stability.

It is known that with heavy use or improper assembly, the tension of these clips decreases. A possible technical solution is to use screw connectors (Minifix or similar) as a replacement or in addition to increase stability.

In general, it is advisable to check the drill holes for fraying. Alternatively, suitable spacers or small wooden shims can be used at the contact points to improve the fit.

I had the same problem once. Replacing the clips with models that have a slightly larger diameter helped me. Otherwise, you can use glue, but be careful not to make the parts permanently glued together.
