This problem is solved by the "window lock"! You can lock the sliding door while it's slightly open, making it ideal for windows that need ventilation, such as bathrooms, kitchens, and toilets. By leaving the window open, you can also prevent burglars and thieves from entering. Highly recommended for security measures for single women, those living alone, and homes with pets or small children! *Please check the installation dimensions before purchasing. [Adopting thick iron material, sturdy and durable] The 2023 improved REBEAUQ window lock uses durable iron material, successfully increasing strength and durability! Also, the installation part of the sash has rubber, so it is less likely to scratch the sash side and is less likely to slip. Highly recommended for rental housing! [No construction required, easy to install] No need to stick or drill, so installation is easy. Insert this product between the outer glass frame of the window glass and the water return part of the rail, then lock it with the knob. The large knob makes it easy to understand the lock/unlock operation, and it's easy to handle.
