Stack your Kallax units confidently without a single new hole in your wall.

This clip locks two Kallax shelving units together using the wall mounting screws that come in the box — no extra hardware, no wall anchors, no drilling into drywall. Print four clips, slot them into the corners between your stacked units, fasten with your leftover Kallax screws, and you're done. If you want extra stability, mounting the topmost unit conventionally should do the trick.

Why makers love this:

• Prints flat on the bed — zero supports needed
• Under 20 g per clip, so a full set costs pennies in filament
• Works with any Kallax size (2×2, 1×4, 2×4 and more)
• Renters rejoice: keeps your stack stable without landlord-angering holes
• PLA works fine; PETG or ASA if you want extra stiffness
• Just 2 clips per stacked pair
• 2 year guarantee*

WARNING! This device has not been tested with loads exeeding those specified by Ikea, and should only be used in situations conforming to the safety information provided by the manufacturer. Do not climb or pull on Kallax units at any time.
