BUTBU Window Restrictor, Child Safety Window Lock, No Drilling (Gray, C)

• 【DURABLE AND STURDY 】Made from selected high-quality nylon, it is resistant to sunlight and temperature fluctuations, maintaining stable performance even after long-term use. The thickened and reinforced lock body is not easily loosened. With a maximum load of 27 kg pulling force, it effectively withstands children’s pulling and impact to prevent window falls and hand entrapment.
• 【ADJUSTABLE】 Using the BUTBU window limiter, you can choose from two different window opening sizes: 9.2cm and 13.5cm. These two modes meet the daily needs of most people. You can easily adjust the opening width according to your needs simply by pushing or pulling the lever. The operation is simple and convenient. And the door and window can be fully opened when fully unlocked.
• 【DUAL UNLOCK DESIGN】Both buttons on either side must be pressed simultaneously to open and close the lock. A unique locking structure firmly secures the locking arm, ensuring a stable lock even when sliding up or down. This effectively prevents children from opening and closing windows without adult supervision. Unlike traditional window limiters, this product requires no key, avoiding the hassle of lost keys.
• 【EASY INSTALLATION 】Two installation methods are provided: tape and screws. You can choose the appropriate method according to your actual needs. Using 3M-VHB strong adhesive, it adheres firmly without drilling and leaves no residue (for best results, let it sit for 24 hours); screw installation is even more secure than adhesive. Furthermore, screws and tape can be used in combination.
• 【 VERSATILE 】 BUTBU window limiters effectively protect children and pets while meeting daily ventilation needs, adapting to various living scenarios. Compatible with most window frame materials, including UPVC, solid wood, aluminum alloy, and plastic.
