Detectable Warning Plates

Our cast iron detectable warning plates are the most rugged, easy-to-install DWPs available on the market today. Our one-of-a-kind detectable warning plates feature a unique boltless locking design that makes proper installation a snap. And because they’re made from iron, Deeter Foundry DWPs wear like iron — standing up to decades of abuse from snow plows, foot traffic and Mother Nature.
