KALLAX Arch Corner Inserts

A softer KALLAX opening

Lightweight corner inserts turn square cube openings into rounded arches. Use two upper corners for a classic arch, opposite corners for a diagonal accent, or four inserts for a fully rounded opening. No drilling or permanent hardware required.

What is included

Your selected 2, 4, 6 or 8 individual corner inserts, in White or Black, with pre-applied double-sided adhesive. Two pieces make one top arch. KALLAX furniture and décor are not included.

Check the opening

Each piece is approximately 167 × 167 × 10 mm. Designed around a nominal 335 × 335 mm KALLAX cube opening; two pieces span approximately 334 mm. Please measure your actual opening before ordering.

Installation

Clean the mounting area and let it dry. Test both pieces before removing the liners. Align with the corners and press firmly for at least 30 seconds. Avoid disturbing them for 24 hours. Dust, grease, residue or textured surfaces can reduce adhesion. Remove carefully to protect delicate finishes.

Material & care

Matte 3D-printed PLA. Fine layer lines and small variations are normal. For indoor use only; keep away from high temperatures and direct heat. Decorative accessory, not a toy. Keep small packaging parts and adhesive liners away from young children.
