Disclaimer:

The purpose of this site is to share information on tests (destructive and shock load) done by Dr. Delbert L. Hall on hardware and materials used in stage and aerial rigging. This site contains the currents results of ongoing research and is not a finished presentation of findings. I make no claim to be a certified testing laboratory. The information on this site may be the results of a small sample of tests and are NOT conclusive evidence of anything – they are just my results. Take them for what they are. Any conclusions drawn from these results are yours and not are necessarily mine.

You should understand that the results from different lots of the same type of hardware/cable/etc. or similar products from different manufacturers might provide different results than the ones that I tested. The data on this site will be updated regularly as I conduct more and hopefully more insightful tests, but I will not attempt to test all sizes of any particular type of hardware or hardware from every manufacturer.

The information on this site is public. If you find it useful, use it. If you do not find it useful, please just ignore it. If you publish anything that uses this information, please give me credit.

This information is intended for theatrical riggers and others who have the training and skill to properly interpret it. If you are not certain that you understand something on this site, or if you wish to make suggestions or report an error of some kind, please connect me by phone at 423-773-4255 or by email at delbert@delberthall.com.

Finally, please be certain that you use an appropriate design factor when selecting hardware for any rigging situation.

Thank you and rig safely!
