WHY YOU NEED IT: To prevent children from frequently opening the oven when adults aren't watching; to prevent children from injuring themselves while playing with the oven door; to protect children from kitchen hazards. HEAT RESISTANT AND DURABLE: You will receive two oven locks. The oven locks are made of PC material, making them safe and durable. When you use the oven, the high temperature will not damage the oven locks or burn your hands. ROTATING DESIGN: Childproof oven locks are designed with two buttons that can be operated with one hand and can be rotated freely 180°. Locking and unlocking can be done with one hand. Press and hold both buttons, then rotate them 90° to unlock, and press the button again to lock. KEEP CHILDREN OUT OF THE KITCHEN: This screw-free safety lock can be easily installed on the oven door so your children cannot open it, ensuring maximum safety! EASY TO INSTALL: Use the durable, heat-resistant 3M tape to install the oven lock without drilling holes or using tools. The 3M tape is very sticky (best after 72 hours). It leaves no residue when removed and does not damage oven surfaces.
