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

• 【DURABLE AND STURDY 】Made from selected high-quality plastic, 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. It can withstand a pulling force of up to 27 kg, effectively preventing children from pulling and impacting it, providing you with reliable safety protection.
• 【ADJUSTABLE 】Featuring an adjustable and detachable structure, it allows you to flexibly set the window opening width according to actual needs and keep the opening within a safe range. The maximum opening distance is 7cm, which is generally smaller than a child's head and shoulder width but larger than a child's arm circumference, thus avoiding the risk of children falling out of the window or getting their hands caught.
• 【DUAL UNLOCK DESIGN 】The upgraded dual-button unlocking design requires pressing two latches simultaneously to unlock, effectively preventing children from opening and closing windows without adult supervision. The unlocking pull force is up to 40N, equivalent to the weight of four 1L buckets. It avoids the risk of window falls structurally, making home protection more reliable.
• 【 EASY INSTALLATION】Utilizing strong 3M adhesive pads, it allows for quick and secure installation without drilling or other tools (for best results, allow it to stand for 24 hours). It leaves no residue and will not damage the window surface. Unlike traditional window limiters on the market, this product requires no key, avoiding the inconvenience of a lost key preventing the window from opening.
