A secret compartment where it's needed. A construction site is bustling with activity from early morning. Colleagues meet on time to receive instructions during the morning team meeting and enjoy one last coffee together. With so many employees needing access to work materials, a secure solution must be found. Keys for the equipment container, forklift, or excavator must be locked away but still accessible to certain individuals. The Rieffel Key Depot KSB-L is designed for storing keys for authorized personnel. With frequently changing groups of people such as tradesmen or cleaning staff, access can be restricted by assigning and sharing a code. Mounted indoors or in a protected outdoor area, the box allows for secure storage of your keys.
