ISC KH407TLP1 Pear-Shaped Large Carabiner

Works like a charm. Sturdy and large enough for what I needed it for. I'm about to purchase another one.

This is a huge carabiner it is recommended for the 3-ply rope on the website but make sure you look at the measurements as it is definitely not necessary to have a carabiner this big for rope. It makes your rigging a lot longer especially if you use a swivel. I bought two thinking they were just slightly bigger than normal but they are huge, so I am going to have to buy new carabiners.

This is just right for the red corde lisse I have just purchased. There is plenty of room for the rope head to go through. I like the locking gate. The small print instructions tell you how to load the carabiner correctly. Money well spent, I bought another.

Captive pin has a tendency to drop out, but excellent as a scaffold hook or an aerial rope hook.
