DISCLAIMER: The information and "backyard science" testing shown in this video is not solid grounds to state a bolt, hanger, or hardware is safe and appropriate to install. It is the developer's responsibility to make the best judgment on up-to-date understanding and practices. Choosing to install and use uncertified climbing/rappelling hardware will raise additional concerns and questions: What is the quality of the raw materials and production method? Is QA(Quality Assurance) and QC(Quality Control) being conducted? What is the AQL (Acceptable Quality Level); meaning is proper testing of a sufficient sample amount being conducted? Does the product meet the requirements for possible certification? If it is certified, are up-to-date certifications provided? Does the manufacturer and/or retailer guarantee quality production? If a bad batch is discovered, will the manufacturer/retailer inform buyers for a product recall?

Developers and installers must also ask: Do I actually know who manufactures the product? Is the retailer I'm buying it from reputable? Is the bolt/hanger/hardware the appropriate choice and metal for the area, (e.g near saltwater)? Am I mixing dissimilar metals? Have I done any personal checking/inspection of the quality, strength, etc? One last note: Strong discretion must be exercised if deciding to use uncertified/untested/unrated bolts, hangers, or hardware that was bought from a hardware-store that you intend to use for life-dependent situations (e.g. climbing, rappelling, rope access)
