[Universal Fit for Vertical & Horizontal Windows] Stop searching for specific kits! This portable AC window kit is designed to fit both vertical sliding windows and horizontal sliding windows. Adjustable from 40.1 "~63.7", it seals the gap perfectly, keeping your room cool and energy bills low.

[5-Layer Heat Shield & Reflective] Unlike cheap plastic panels, our air conditioner window seal uses silver-plated, airtight fabric. It reflects thermal radiation and blocks UV rays while allowing soft light in. Say goodbye to dark, stuffy rooms and hello to bright, efficient cooling.

[6.8" Wide Outlet for Maximum Airflow] Features a 6.8-inch diameter exhaust channel compatible with 99% of portable air conditioner exhaust hoses. The wider opening prevents back pressure, ensuring your AC unit runs smoothly without overheating.

[Secure Seal with Elastic Bands] The pipeline channel includes high-quality elastic bands and buckles to tightly grip the hose. This AC window vent kit stays firmly fixed, preventing gaps and stopping hot air from seeping back inside, even in windy conditions.

[Tool-Free Installation & Trim-to-Fit] Includes strong adhesive backing tape for easy setup—no drilling required. The 10.2" wide panel can be trimmed to fit unique window tracks. Double-layered stitching ensures durability season after season.
