Latching hooks

How did teams design hooks that latched onto climbing bars in the past? My team is trying to design one but we weren’t sure where to start. Are there any specific teams we should look at or research?

I have seen handcuffs used during Stronghold as latching hook. Local Sheriff’s Department was willing to donate.

Carabiners? I know 2502 used them in 2016, probably others as well.

You might look at the design of a residential wooden gate latch as a starting point.

118 in 2016.

I remember seeing 842’s in action at Las Vegas. It was pretty effective too.

This is intriguing and sounds cool. Do you know what team it was?

a gate latch is probably a better choice.
