Brady Signmark's new SHOCK-STOP(R) lockout hasps give strong visual warnings to workers near a machine under lockout. The bright red stop-sign-shaped hasp allows up to six workers to lock out a single energy source with individual padlocks. The 13-gauge zinc-plated steel SHOCK-STOP hasps are virtually tamperproof and include front and back labels.Brady Worldwide, Inc. - Signmark, Milwaukee, WI.
