The GBruno 4-piece magnetic cabinet lock set is designed to keep children safe by preventing access to drawers and cabinets containing potentially dangerous items like scissors, medications, or cleaning supplies. Each lock uses strong magnetic technology that works with drawer doors up to 1.38 inches thick, and the included magnetic key allows adults to open cabinets easily while keeping little hands out. The locks install without tools using durable 3M adhesive tape that bonds securely without drilling or damaging furniture finishes. Installation is flexible with three mounting options at the top, bottom, or side of drawers, and the locks can be positioned in any 360-degree direction to fit your cabinet configuration. Once installed, the locks remain invisible from the outside, preserving the aesthetic appeal of your furniture while providing essential childproofing protection. This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm under Proposition 65. Each set includes four magnetic locks with latches, one magnetic key with holder, and an auxiliary installation tool to help with precise placement.
