Safety-geared, trapped keys

Company’s trapped key interlock systems ensure a predetermined safety sequence each time hazardous equipment is accessed or operated. To meet the needs of more challenging environments, the company has extended its Standard Duty (SD) brass interlocks with Medium Duty (MD) and Heavy Duty (HD) Series, equal to extremes in temperature, weather, dirt, and corrosive elements.INNOV-KirkKey-400

The MD and HD Series interlocks use 316 stainless steel cylinders, keys, bolts, and inner-workings that withstand high temperatures and corrosives in outdoor or harsh environments. The cylinder mechanism has no openings and few moving parts. The shaft driven design prevents dirt and debris from clogging the mechanism. Gasketed keys and dust covers on the interlocks further protect the cylinder from debris.

The HD Series is constructed of 316 stainless steel, including the lock body; passivating electropolishing further protects the interlocks from chemical activity. The MD Series are constructed with a brass lock body protecting the inner-workings. The 316 stainless steel dowel pin key design used in the MD and HD series is stronger than typical pin tumbler keys to resist breakage and damage. The dowel pin design cannot be duplicated or altered to create a master key. Its distinctive shape is less likely to be misplaced or slip through standard floor gratings, minimizing the incidence of lost keys.

MD Series and HD Series ranges include mechanical and electromechanical bolt, access, transfer and valve interlocks, along with a full range of accessories to form a comprehensive interlocking scheme. — Kirk Key, 234/209 9301;
