A lot of people use carabiners in the entertainment industry. But do you know how to verify if a carabiner is good to use? And if you are using them, do you know how to ensure that you are using them correctly? Here are a few basic tips on verifying the rating on your carabiner and in what situations you would use an oval frame over a D-Frame.
ANSI Z359 Standards for Connecting Components
Compatability is the geometric relationship between two connecting pieces. In other words, how well do these pieces fit together? How easy is it for the connector to side load? Is there any possibility of rollout (unintentional disengagement)?
Tips for making a compatible connection: If you find your connector in the perched position, you can improve your compatibility by using a different connector or adding a soft link between your connector and anchor. The soft link will add flexibility to the system which is key for any compatible connection.
Why does shape matter? When rigging and building fall protection systems selecting components that produce safe, simple and clean systems is key. Let’s look at the Off-Set D and Oval carabiners, for example, and see how their shape produces different results.
Notice the fleet angle in the pulley with the Off-Set D. Due to the design of the carabiner, one side of the pulley is higher than the other, thus causing the rope to rub on the cheek plate. Switching to an oval shaped carabiner eliminates the fleet angle and the friction that it causes.

Working At Height: What’s In Your Rigging Kit?
Trevor started a career in rigging after completing an internship with Cirque du Soleil. He was hired as an on-call Rigger at "Viva Elvis". After a year as an on-call, he was hired to tour with "Corteo" on the European leg of the tour. As a young rigger, for Trevor, this show was like going to university. It was full of professional and personal challenges that became some of the most influential moments of his life. In 2012, Trevor was hired to do the creation of Michael Jackson "ONE" in Vegas. Currently, Trevor spends his time bouncing back and forth between rope access projects on stadiums, bridges and wind turbines and work-at-height training. He owns a company called Rope Technologies based out of Las Vegas and they teach riggers how to work-at-height safely. Trevor's goals are to push the overall safety of work-at-height industries with a specific focus on theatrical safety. Trevor is married Noemie Dube-Dupuis and has 3 kids, Lola, Theo and Mila. They reside in Las Vegas.
