Finally, a practical window solution for your shed, chicken coop, RV, or basement! This horizontal sliding window features a locking design that lets you open it halfway or fully, giving you complete control over ventilation while keeping insects out with the included screen. Made from rust-resistant aluminum with 5mm thick tempered glass, this window is built to withstand harsh weather conditions while providing excellent natural light. The 3-inch wide frame offers durability without being bulky, and the tempered glass is much safer than regular glass - if it breaks, it crumbles into small pieces rather than sharp shards. The best part? You can customize the size to fit your specific opening! Just measure your window space (width and height at the narrowest points) and they'll create a window that fits perfectly. Installation is straightforward with the included screw kit - simply embed the window into the opening, screw the frame in place, and fill any gaps with foam adhesive. Perfect for improving airflow and lighting in sheds, playhouses, chicken coops, barns, garages, basements, cargo trailers, and more. No more stuffy, dark outdoor spaces - this window transforms them into functional, comfortable areas. The sliding mechanism works smoothly, and the locking feature provides security when closed. Whether you're a DIY enthusiast looking to upgrade your outdoor structures or a homeowner needing better basement ventilation, this window delivers professional results without the professional price tag.
