This tool is specifically designed for telephone craftwork, making it easy to connect wires to fuses, tighten nuts on binding post terminals, and place fuses in cable terminals. Featuring double-ended hex sockets (3/8" and 7/16"), the color-coded ends allow for quick identification of socket sizes. The design enables the use of a wrench for additional torque, providing extra leverage when needed. Manufactured from high carbon tool steel and heat-treated for maximum strength and durability, the sockets feature a thin-wall design to access tight spaces with ease. The rugged high-impact extruded plastic handle ensures a comfortable grip for long-lasting use. Perfect for accessing telephone boxes and pedestals, this tool is an essential for any technician.
