ᐅ Who uses KALLAX as a pass-through shelving unit – and how do you reinforce the shelf for stability?

Hello everyone,

I’m planning to use a KALLAX shelf unit as a pass-through between the kitchen and dining room. The idea is to install it as a kind of room divider, allowing access through the open compartments—sort of a modern take on the classic pass-through window.

My main question is for those who have done similar projects: How do you stabilize the KALLAX shelf in this type of setup? Since it’s used as a pass-through, it will experience some load, for example when placing dishes or from people leaning on it repeatedly. I’m wondering if the usual wall fixings are sufficient or if additional reinforcements are advisable.

I’m especially interested in your approaches to improving stability and sturdiness. Do you use extra brackets, different materials, or maybe wooden panels for reinforcement? How do you make the shelf moisture-resistant and secure against tipping?

Thanks for sharing your experiences and tips!

I attached my KALLAX to the wall using L-brackets and installed two sturdy wooden battens underneath. This way, the shelf is very stable and does not wobble.

Hello Lucasi,

I find the experiment with using KALLAX as a pass-through very interesting! Basically, the shelf is not designed as a free-standing wall opening, so securing it firmly to the wall and floor is very important.

For stabilization, I recommend the following: Be sure to attach the KALLAX to a solid wall using strong anchors and brackets. If the shelf’s back panel is present, I would additionally reinforce it with wooden boards and screw them to the wall and floor.

Screwing the individual elements together can also improve stability. If the pass-through is larger, you should also consider a supporting batten along the bottom edge, possibly as a baseboard.

Do you already have specific dimensions, and what kind of flooring do you have? On carpet or uneven tiles, you need to work with even greater precision.

Basically, when using KALLAX as a pass-through, it is advisable to install a cross brace. A centrally placed wooden panel behind the shelf works well for this, providing increased stability and preventing wobbling. Securing to the floor and wall with brackets is also essential.

Additionally, small brackets can be installed under the shelf to prevent tipping. Especially if the shelf is frequently used as a pass-through, strong anchoring at multiple levels is recommended.

Thanks for the tip; I hadn’t considered the back panel before. I was thinking more along the lines of extra metal brackets, but a wood panel does sound practical, as it also creates a more visually appealing surface.

Cross bracing and central wood panel

Could you provide an example? Is it better to have a panel covering the entire back of the shelf, or would a partial panel in the middle be sufficient? The shelf measures 77 x 147 cm (30 x 58 inches) (WxH).

I’m curious whether combining brackets and a wood panel will be enough, or if adding base elements as a support is also advisable.

I am using a KALLAX as a pass-through in my home. I secured the shelf to the wall on both sides with metal brackets and additionally attached small wooden strips underneath as baseboards. This provides good stability.

I have not installed a full wooden panel at the back, but that could be recommended for wider units.
