## Questions & Answers

**Q: What is the difference between “one size”, “screw lock” and “triact lock”??**
A: Not sure about one size, screw lock- it has a s screw lock on the gate of the carabiner, and tract lock is a triple locking action on a carabiner.

**Q: I would like to purchase 5 caribeners that have the green button dual lock system. which option do i choose? one size, screw lock or triact?**
A: The one you are looking for is the ball lock, which we currently do not have.  We have the screw lock in stock.

**Q: will this work with a Sterling ATS?**
A: I am familiar with the Sterling ATS, but have not tried to use the Petzl with it. I suspect it will work/fit the connection hole in the Sterling.

**Q: This picture is not the petzl am'd pin  lock, which product would i receive the am'd pin lock or the boll lock shown?**
A: You would receive an AM'D Pin-Lock. We're working with Amazon to have that image corrected. Thanks!
