Hi guys,

Thank you for your advice.
Drat that the pic didn't show up. They are made up of black electrocoated square tubing about 5/8" od in 4x8' panels. Each crossing interval is about 6". At 1st I thought they were possibly aluminum because they felt pretty light. But when I got them home I tested with a magnet and it was magnetic.

They are not the strongest window bars but my hope is that they will act as a visual deterrent to cause criminals to look for an easier target and pass on us.

Thanks for the mention of being able to exit from a barred window in case a fire has prevented exit from the doors. They are not hinged but we have 3 other exits from upstairs where we are 99.9 of the time.
