Fastlinks are an easy way to join or tension wire. You simply push your wire or cable into the ends, leaving at least a two-inch tail which will allow for easy adjustment or re-tensioning. Once in position, serrated rollers grip the wire as any reverse tension is applied. To increase wire tension, simply pull the wire through even more. To remove the Fastlink, cut the wire, pull the loose ends through, and you are ready to use the Fastlink again. Three sizes are offered, allowing them to be used on smooth wire from 16 to 7. 5 gauge ranges as well as 15. 5 to 12. 5 gauge twin strand barbed wire. A tensioning tool(TGT)is also available for application where high tensions are required.
