This fills a need I've had for years. If you're working in tight spaces with smaller connectors, a full-size wrench or duct lock won't always fit, but this will do. I've been using this to disassemble and reassemble fittings for the last month and I have no regrets. The open end grips a piece of threaded rod or a small nut, but the thin, adjustable end is the key to this tool.
