November 6, 2013 – FSR’s Dr-Sock is a cable-pulling tool designed to simplify and accelerate every installation requiring cables and connectors, which claims to protect cables and connectors from being damaged by taking the stress off the connection points while pulling through a conduit.

The design opens up to 1.25 in. and features brightly coloured sleeve tips for simpler identification, and a steel ring to allow positive attachment of a pull snake. Dr-Sock can also be used to safely pull FSR’s digital ribbon cables, as well as others with connector shells.
