Abstract: A guard assembly can be positionable in an installed position between a first roller and a second roller of a roller conveyor system. The guard assembly can include a first frame having a first contour shaped for receiving at least a portion of the first roller. The guard assembly can further include a second frame having a second contour shaped for receiving at least a portion of the second roller. The guard assembly can also include a biaser between the first frame and the second frame so as to urge the first frame toward the first roller and the second frame toward the second roller in the installed position.
