The 3M™ Disk Marker provides an easy and accurate method of precisely locating flush-mounted facilities, which become covered by backfill. Markers provide accurate identification of buried water lines, helping to reduce the risk of accidently excavating other buried facilities. The four-inch disk marker is easily fastened to the underside of non-metallic lids or covers over flush-mounted facilities, such as hand holes, manholes and other grade-level enclosures during construction and maintenance. Disk Markers are not intended for direct burial.
iD Markers can be programmed to include customer-specific information, such as the facility owner, conduit size, placement date, and other important details. This information can be accessed and changed by 3M locators with the iD function. This can all be done without the need for an external power connection.
