“Worthless... the gripple medium had better holding strength and did not fail. These would not even come close to tightening without the guts coming loose... and we were not putting that much tension on the considering their rated limit.”
“These are so simple to use and no crimping tool required. The best part is they can be used over again, just push the wire through and you are ready to go. No need to worry about the wire slipping out. We used these to join our Electralock fence section together and none of the Fastlock splicers have come loose.”
“I use these quite often fasting wire around trees to run 1" plastic pipe tethered with wire ties to collect maple sap. I use these specifically because they don't break or slide on the wire. The fastlock has 4 teath, and it grabs very consistently without sliding or breaking.”
