Abstract: A clamp includes a body, a channel, an opening and a clamping member. The body includes a first end, a second end, a first side, and a second side. The first side extends between the first end and the second end. A longitudinal axis extends between the first end and the second end. The channel extends through the body in a direction transverse to the longitudinal axis, and the channel includes a plurality of curved inner surfaces having different radii of curvature. The channel is positioned adjacent the first end. The opening extends between the first end of the body and the channel, and permits a portion of a cable to be laterally inserted into the channel. The clamping member is positioned adjacent the first side of the body and is capable of engaging a support member. The clamping member is configured to bias the support member against the first side.
