【FRESH AIR, CONTROLLED OPENING】: Open a sliding window or raise a compatible single- or double-hung window for a breeze, then use the sliding window security bar to help limit how much farther the sash can move. Enjoy airflow without leaving the window free to open wide.
【VERTICAL OR HORIZONTAL USE】: Install the adjustable window bar vertically in the track of compatible single- or double-hung windows, or horizontally in sliding windows. It may also fit some sliding glass doors when the available space measures 17–32 in. Measure between firm contact points before ordering.
【STAINLESS STEEL, EXTRA BARRIER】: Street-facing windows and ground-floor rooms can feel exposed. The square stainless steel window locks sits inside the frame to help resist unwanted sliding, adding a physical obstacle against entry.
【FOR HOMES WITH KIDS & PETS】: Curious hands or paws can push at an open window. When properly fitted, this window bars security inside helps limit sash travel, so you can choose a smaller opening. Always supervise children near windows.
【RENTER-FRIENDLY & TRAVEL-READY】: Add an inside window stopper without drilling holes or permanently altering the frame. Easy to remove and reposition, it can also travel with you for added peace of mind in compatible hotel or vacation-rental windows. Press the spring button, choose from 12 positions and turn the rubber foot until snug.
