Post box key safe – flexible installation without drilling

In Switzerland, installing a key safe inside a post box (Milchkasten) has become a practical and discreet solution for shared access.

Traditional installations using screws or adhesive provide a very strong and permanent fixing, but they are not always suitable—especially in rental properties or where flexibility is required.

This is why Velcro-based installation has become increasingly popular. It allows a clean, no-drill setup that can be removed later if needed.

Even more robust models such as the Supra S5 can be used in this type of installation when an appropriate fixing is used, offering a balance between higher security and flexibility.

The choice between glue and Velcro ultimately depends on whether you prefer a permanent installation or a more adaptable solution.
