Collection: Call 811 Before Digging Signs

Call 811 before digging signs on 8x12 rust-resistant aluminum, for buried electric, gas, petroleum, steam, water, and fiber. Post them at duct banks, pipeline right-of-ways, vault lids, valve boxes, and any corridor where an excavator could strike a live utility.

One damaged line costs far more than the signage that would have prevented it. These are printed on .040 aluminum with UV-stable inks and pre-drilled mounting holes, built to stay legible on a post or fence line through years of outdoor exposure. Made in the USA by CGAP Safety.
