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.
