Prodigy SG-1 - Screw Gate Steel Carabiner

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.
