ABM-90 / DR-4 with IW-1000+ frame for very large diameters

When lateral connections or poor interior condition force you to ‘stay low’.

Besides the standard range of centralized and invert wheel sets for the ABM-90 and DR-4 mapping systems, the IW-1000+ frame is specially designed for mapping sewers, stormwater pipes and culverts with diameters larger than 1000mm / 40”.

The frame can be folded so that is fits through standard street level manhole entrances, eliminating complex and time-consuming assembly downhole.

Foldable design for easy access through standard manholes

No aboveground tracing required

Highly accurate inclination data.
