Product Description
Protex SDB-106 Tall Drop Box with Dual Key access
Tubular key lock instead of a standard key — harder to pick, harder to duplicate. Same steel drop box concept but with better lock security. If the drop box is in a public area or you are worried about unauthorized key copies, the tubular lock is worth the upgrade.
