Varipole safety precautions? in Grip & Rigging Posted Thursday at 03:30 PM Additional info: Setting these up has been a 1-man job so far. I'm able to get them nearly level but not perfect. How essential is it to get it right on the nose? Also when I put in the lock to do the final extension to wedge into the ceiling, is there such a thing as over extending them into the ceiling? Or the tighter the better?
