Huge swings in the outdoor temperature are the norm in Texas, but you can hang this thermometer in any outdoor space, anywhere. We think it'd look good on a lanai or a patio. The sign is approximately 18 x 18 x 2. No batteries needed. The face and hand are protected by a piece of clear plexi. And just for fun...our temperature controlled facility stays right around 78 degrees. Get your hands on this outdoor art. We don't keep many in stock, but don't let that stop you for placing a backorder. We'll confirm availability and get it out the door in a hurry.
