A cable lubricating device and method, for use in cable through conduit pulling operations. The automatic cable lubricating device includes a lubricant supply tank having an internal chamber and a regulating means for regulating the flow of a pressurized lubricant from within its internal chamber, a lubricant dispensing head having a cable feeding aperture therethrough and a plurality of lubricating ports, and a flexible lubricant supply hose having a first and second end. The dispensing head further includes an input port. The first end of the supply hose has a connecting means for connecting to the regulating means downstream of the supply tank. The second end of the supply hose has a connecting means for connecting to the dispensing head input port such that a lubricant under pressure stored within the internal chamber of the supply tank may be dispensed through the lubricating ports. The regulating means may be adjusted to control the output of lubricant from the lubricating ports. The dispensing head includes a conduit attachment means for attaching the dispensing head to a conduit such that in use the lubricating ports dispense the lubricant into the conduit so attached.
