This product from Outwater seems like it warrants a second look. I have seen these in use in permanent installations, and on-stage for scenery. When I last did a set that used cable as a detail on the railings we used another connector (verlocks - http://www.versales.com/ns/specialty/verlock/verlock.html). The verlocks in this instance were a little clunky to work with, and I like the look of the Outwater projects. The fun of being a TD is finding new toys and being able to come back and rethink technical solutions!
