ᐅ Why does the left door on the Kallax close differently from the right one?

Hello everyone, I’ve been wondering for a while why the left door on my Kallax shelving unit closes differently than the right door. Specifically, the left door has some resistance when closing and sometimes doesn’t sit flush with the frame, while the right door closes almost perfectly and aligns flush. Both doors are officially from the same manufacturer part. Does anyone know any technical reasons for this? Could it be a construction defect, an adjustment issue, or is the left and right design fundamentally different? I would appreciate any insights on differences in hinge mechanics, installation instructions, or experiences, as I want to understand the problem myself before undertaking any major modifications.

The hinges on Kallax units are usually designed symmetrically. Often, the issue is due to installation or slightly warped doors. Check if all screws are properly tightened and if the door is correctly aligned.

First of all, thank you for the detailed question, it is very helpful. Kallax doors often have slight manufacturing tolerances on both sides, which can result in different closing behavior. Here is a brief overview of why the left door may close differently than the right:

1. Hinge mounting: Kallax doors usually use clip-on hinges that are reversible to function as left or right. However, the hinge adjustment can vary if they are not precisely aligned.

2. Screw position: Small deviations in the screw fastening affect how the door fits in the frame.

3. Door material: Due to wood veneer or MDF warping, a door can be slightly distorted.

4. Magnetic catch or damper: Sometimes only one side has a damper or magnet installed, which significantly influences closing.

Tips: Open the left door, slightly loosen the hinge screws, gently adjust the door to center it, and then check the closing behavior. If available, also check the pressure adjustment screws on the hinges, as gap dimensions can be adjusted there.

In summary: Technically, the doors are usually identical; differences mostly arise from mounting and adjustment, and less often from differently installed components.

I had to learn this myself. At first, I found it frustrating how different the doors seemed. But after I loosened and readjusted the hinges, things improved a lot. Sometimes it helps to take your time and go through it calmly instead of immediately assuming that a part is defective. 🙂

The difference is technically based on the fact that Kallax doors are designed uniformly for both left- and right-hand hinges, but the functionality is determined by the hinge adjustment. The hinges typically have three adjustment screws: vertical, horizontal, and depth adjustment. If any of these screws are unevenly or incorrectly adjusted, the closing behavior changes noticeably.

Additionally, small manufacturing tolerances in wood materials like MDF or particleboard can cause a door to be slightly warped, which can lead to it sticking. The way the door is attached at the back of the shelf unit can also cause it to tilt.

Another factor is the load or wear on the hinges. If the left door is opened more frequently, the hinges may loosen slightly or adjust differently.

Conclusion: The doors are not fundamentally designed differently; rather, the adjustment and installation affect the closing behavior.

Thank you for the technical explanation, that really helps me. Until now, I have only adjusted the outermost screws and haven’t fully utilized all the adjustment options.

What exactly do you mean by depth adjustment on these hinges? I assume it relates to how far the door protrudes into the frame? Or does it also affect the pressure or sealing when the door is closed?

And how can you tell if a door is causing problems due to warping? Are there simple tests that can be done with basic tools?
