Stanley STMT86001-8B 1/4 Inch Drive Flexible Extension 150 mm

The Stanley STMT86001-8B is a 150 mm flexible extension with a 1/4-inch square drive. Unlike a rigid bar, a flexible extension can bend, so it reaches round obstacles to fasteners that are not in a straight line from the ratchet. It is part of Stanley's 1/4-inch accessory range, which also has 50 mm and 100 mm rigid bars and is marked as exceeding the ANSI standard.
