Lineman Overhead Material List Practice Test

A strand vise is a device used to terminate a guy wire at the anchor and hold it under tension, functioning as an automatic dead end for the strand. It grips the wire as tension is applied, locking the strand in place so it won’t slip. The sizes listed, 3/8" or 7/16", match common guy-wire diameters, making it fit the typical hardware you’ll encounter in field work. This specific purpose—terminating and securing the guy wire at the anchor with an automatic grip—is what sets it apart from other hardware like splice clamps (used for joining conductors) or insulating links (which isolate electrically).
