Non-Drill IKEA Kallax Shelf Stacker Connectors

Secure Stacked Kallax Units Without Damaging Your Walls

Stacking IKEA Kallax shelving units is a great way to double your storage, but preventing the top unit from shifting or toppling usually means drilling holes into your walls.

These custom-engineered 3D-printed connector clamps provide a rock-solid, non-destructive solution. Designed to bridge and clamp adjacent shelf walls securely, they lock stacked units together without the need for wall anchors or permanent modifications.

Key Features

• No Wall Drilling Required: Ideal for rentals, temporary setups, or anywhere you want to avoid wall damage.

• Precision Fit: Custom-contoured to fit snugly over two stacked 37mm thick Kallax outer walls (74mm combined total thickness).

• High-Grip Clamp Design: Locks the upper and lower units together to prevent shifting, sliding, or accidental tipping.

• Optional Screw-Mounting: Features integrated mounting points if you choose to screw the clamps directly into the shelves for maximum rigidity.

• Durable 3D-Printed Build: Engineered for strength, tough daily use, and a neat, low-profile finish.

Important Fitting & Preparation Notes

• Measure Before Buying: Designed specifically for standard Kallax walls (37mm individual / 74mm paired). Please check your shelf thickness prior to ordering.

• Remove Felt Pads: Ensure any felt feet or buffer pads between the stacked units are removed before installing for a flush, secure clamp fit.

• Custom Sizes Available: Have an older Expedit unit or a different shelf thickness? Send a message with your measurements and a custom set can be made to order.

• Color Options: Supplied in standard colors. Custom colors are available upon request—contact us prior to ordering!

Safety Notice

These clamps are designed to stabilize stacked shelving and prevent top units from sliding or shifting off the base. They are not a structural wall-anchoring safety device and will not prevent tipping if pulled on directly. Do not climb or allow children to climb on stacked units. The seller accepts no liability for misuse.
