We made tree swings with the Scouts and used these clips to quickly attached the swings to the rope. As darkness fell, the Scouts managed to lose one of my devices in the long grass, so sought a quick delivery from Amazon so the second troop session two days later could use the same activity.
This multi-pack worked well as it meant I could run a third swing. The locking design meant there was no chance the gate could open. The shiny black finish looks smart. Many of the carabiners listed were not CE rated or could potentially be fake, I was able to verify this one and noted that there were almost 1500 reviews that were mostly positive.
