ABSTRACT:
A handle of a friction lack comprises a body having a threaded portion extending along an axis for threadable connection to a bolt of the friction lock such that rotation of the body in a first sense advances the body on the bolt and rotation of the body in a second, opposite, sense withdraws the body from the bolt. The body extends along an axis which is transverse to the threaded portion axis. The body has a first end and an opposite second end lying on the transverse axis. A first ear extends from the first end and makes an angle with the transverse axis to cant toward the first sense of rotation and a second ear extending from the second end and making an angle with the transverse axis so as to also cant toward the first sense of rotation.
