I've been looking for cable retractors that don't catch and dont bind up on themselves when retracting and have had no luck. We've been using modified retractors from hardware stores on electrified flown scenic pieces. They arn't really working for us. They work enough, but I was wondering if anyone knew of a better product. We're in the round and we can't really swag cable because it will get caught up on the truss or the flown pieces themselves.
