A Window Frame Thermometer makes reading outdoor temperatures easy. Now you can see the temperature outside from the inside of your house. The thermometer features a patented wall mounting bracket that may be mounted and aligned, either on the right or left of a window frame, allowing it to swivel up to 90° to accommodate viewing from any angle. It is constructed of medium electric blue anodized aluminum to withstand the elements and the scale is imprinted with a bi-colored graduation (black for the normal range, and red for the dangerous, e.g. frost).
