Abstract
Abstract A guide is used for simultaneously laying a plurality of cables in a conduit. The guide comprises a body portion sized to fit within the conduit, the body having a plurality of longitudinal channels along its periphery for forming a plurality of spaced-apart cable guide passages in cooperation with the internal wall of the conduit. A lubricant can be introduced into each channel.
