The present disclosure relates to a gripper assembly for handling continuous rod. The gripper assembly may include a gripper face with a gripper profile forming a surface in the gripper face and a texture on a portion of the surface. The texture has a plurality of ridges having a yield strength sufficient to transfer a shear force to the gripper assembly at least as large as a weight of a continuous rod.
