A secret compartment where it's needed. A construction site is bustling with activity from early morning. Colleagues gather punctually for the morning team meeting to receive instructions 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 need to 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 workers such as tradespeople 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 the secure storage of your keys.
