Protecting equipment and workers from errors during electrical and switchgear maintenance, the Kirk Key HD Series Type DM access interlock ensures steps cannot be skipped and a pre-determined sequence of operation is followed. Made entirely of electropolished 316 stainless steel, it can be used in high-temperature or corrosive environments. The key and cylinder mechanism has no openings and few moving parts. The shaft-driven design resists dirt and debris; the gasketed key and dust cover prevent debris from entering the interlock cylinder.
