The phrase refers to a hook or hanger designed to hold a framing nailer, typically purchased from a home improvement retailer. These hooks provide a convenient means of suspending the tool from a belt or rafter, keeping it readily accessible while working on framing projects. For instance, a carpenter might use one to keep their nail gun within reach while constructing a wall frame.
This accessory enhances efficiency and safety on construction sites. By keeping the tool close at hand, it reduces the need to repeatedly bend down or reach for it, thus minimizing strain and preventing potential injuries. Historically, tradespeople often had to improvise methods for tool storage while working at height or in confined spaces; these purpose-built hooks offer a more secure and ergonomic solution.
