The Fremco Locking Pin, Long (Millennium part #658469, vendor #103-10176) is a replacement component used to secure cable blower accessories firmly in place during fiber optic cable installation. Its extended length and sturdy steel construction ensure a positive lock under the vibration and pressure generated by cable blowing operations, preventing accessories from loosening mid-run. Compatible with Fremco's line of cable placing tools, this pin is an inexpensive but essential spare part for crews maintaining blower equipment in the field. Keeping a supply on hand helps installation teams avoid downtime and maintain consistent, safe performance on fiber builds.
