Safewell’s Biometric Hub Lock (Bio-Hub) provides Biometric lock technology to long gun safes! This breakthrough concept allows for individual personal fingerprints to open your safe. It provides for a sleek new look in long gun safes as it eliminates the need for a lock on the outside. Of course, it still comes with an emergency backup key to open your safe. You can store/program up to 50 fingerprints. This enables you to program multiple fingerprints of yours and any other people you authorize.
