The Harloff Field Install Retrofit Kit provides a pre-engineered lock upgrade package designed to convert legacy mechanical and electronic locks on mobile medical carts to modern Harloff 41032 electronic keyless entry systems. Engineered for on-site installation by facility maintenance teams and biomedical engineers, these kits allow healthcare institutions to update access security without removing carts from clinical service. The 41032 series lock assembly replaces older 41043 and 41046 lock mechanisms, introducing programmable numeric PIN access, supervisor master code overrides, and automated relocking capabilities. By standardizing cart security across legacy fleets and specialized SL (Slim Line) cart series, these field-install kits eliminate physical key tracking vulnerabilities, streamline nursing access, and enforce strict regulatory compliance for medication and clinical supply storage.
