I want to use J hooks (or something similar) to elevate all my new LV wiring off of the attic floor. I've got plenty of rafters, braces, etc. that I can attach the J hooks to, but all of the J hooks I've seen look to be for commercial/industrial use where everything is at right angles, beams are available to clamp on to, etc., or they use threaded rods or cables for hanging. They also look like they would be difficult to bend/twist.
Are there any that are a bit flexible so that they can be bent after being nailed to a rafter, etc. to get the "carrier part" correctly positioned? Essentially none of the framing members in my attic are close to being vertical, horizontal, etc., because they all follow the slope of the roof (or are complementary to the slope).
