A dropped wrench from a scaffold can kill. A hammer slipping from a ladder can cost you a client. Tool safety tethers are the primary defense, but the market is full of conflicting ratings, cheap knock-offs, and one-size-fits-all advice that gets people hurt. This handbook cuts through that noise with a plain-language, engineering-based approach to the entire category.

You will learn how tethers are actually rated and tested, how to match a tether's working load limit and cord length to a specific tool and job site, and how to install and inspect them so they perform when something slips. The book also covers the commercial side: how brands are positioned, what a typical reseller margin looks like, and how to build a service business around tether inspection and replacement.

Written for professionals, safety managers, and serious enthusiasts, this is a reference you will keep in the truck, not on the shelf. It uses concrete examples, clear tables, and practical checklists — no filler, no hype, just the knowledge needed to make a job site safer and a tether purchase count.
