Below is a list of Lathe Guards manufacturers from Mystic, Connecticut. Lathe guards are visors or shields that act as point-of-operation protective barriers that guard workers and operators when they are in close proximity to a spinning lathe. They prevent accident or injuries caused by debris, chips, shavings and broken tool bits flying at high speeds. Lathe guards also keep fingers a safe distance from the lathe, which spins at very high RPM (rotations per minute).
