Product Description
Protex SDB-100 Small Drop Box with Tubular Keys
The cheapest way to secure cash and keys behind a locked steel door. The SDB-100 is a basic wall-mount drop box with a key lock — mount it in your back office and have employees drop tips, keys, or cash through the slot. At $95, property managers buy a handful of these for apartment complexes and never think about them again.
