HD Keys


HD Series keys are made from electropolished 316 stainless steel and are constructed to be robust in the toughest of environments. The shaft driven design contains precision drivers (dowel pins) configured to specific combinations. They will not snap under force, nor will they fall through standard floor grating, minimizing downtime due to key replacement. The unique design prevents key duplication or unauthorized mastering, ensuring the highest protection of your interlock scheme.

For further technical information please refer to the datasheet.
