The 200 Keys Adjustable with RFID Lock from Barska (Grey) features a hook-style cabinet that makes key organization easy and convenient. Inside the cabinet are 20 rows of color-coded and numbered hooks, each of which is easy to access and keep track of, thanks to the included key index. The two-sided indexing chart has ample room to document the keys hook position corresponding lock, and a drop-in plastic sleeve tethered to the hinge inside the safe provides a hands-free reference. The safe has four pre-drilled mounting holes and included hardware for installation. The RFID locking system allows quick and easy access to the cabinet using the included five programmable keycards.
