Prodigy Steel Oval Carabiners

The Prodigy Screw Gate Steel Oval carabiners have a simple screw-locking gate that is easy to use and represents the best-value carabiner for most situations.

Screw gate carabiners have a simple threaded gate mechanism. Screw the gate tight to close and orient it so you are screwing down towards the ground.

"Screw down, so you don't screw up" is a handy way to remember which way the carabiner should be oriented, with the idea being that gravity would prevent the gate from opening due to vibrations. 

In practice, as with any carabiner, you must check your rigging before and after each use.

You should ensure that nothing comes into contact with the gate while in use.

Triple-Action carabiners have a super-secure gate that requires three actions to open. Slide the gate, twist the gate, and then open the gate. When the gate is released, it automatically locks, requiring the
three actions to open again.

Triple-Action carabiners are an excellent choice for several rigging applications:

• Where the user has a high chance of coming in contact with
  the gate
• Where there will be repeated shock loading
• Situations where, due to height/access, it's not possible to check the gate is locked every time

Compared to a double-action locking carabiner, the main downside for aerial riggers to consider is that they are more challenging to open with one hand.
