disk Markers are used to electronically mark underground utilities to prevent accidental damage or incidental contact and facilitate easy location and service of vital underground assets.
disk Markers are primarily suitable for direct burial over the utility to be marked up to a depth of
5’(1.5m). The marker can be accurately detected even if level of marker is 60o offset with respect to ground
level.
disk Markers can be rigidly screwed on to the inner side of all standard non-metallic manhole
covers using provided integral mounting tabs or by using the optional hole location provided in the centre
of the marker casing. Each without requiring any additional brackets & their associated costs.
disk Markers are available for marking all standard utilities & are compatible with industry standard
