Abstract: A ratchet assembly is configured to rotate a fastener in both a clockwise and counter-clockwise direction. The ratchet assembly includes a yoke, a drive, a left pawl, a right pawl, and a shuttle assembly. The yoke defines a fastening hole. The drive is rotatably coupled to the yoke and is supported in the fastening hole. The left pawl is supported in the yoke and is biased toward the drive by a first biasing member. The right pawl is supported in the yoke and is biased toward the drive by a second biasing member. The shuttle assembly is rotatably supported in the yoke between the left and right pawls and selectively engages the left and right pawl. The directional knob is coupled to the shuttle assembly.
