A Hawke HM sealing module consists of two halves, and has removable layers and a center core. Thanks to this technology called Multi-diameter, one single module can seal a cable or pipe over a span of several different diameters simply by peeling layers from the module halves. This ensures a perfect fit. Frames of Hawke product H are filled with standard HM modules at 60 millimeters depth, which together cover a diameter range of 3 to 99 millimeters.
