This 48 key, blue, Steel Secure Key Cabinet with Combination lock is super durable. It's small and compact, yet very secure and holds 48 keys. It mounts directly to the wall and has the holes predrilled. Which made install a breeze. It includes cards for the keys and labels, and even though the box is small it's very strong and durable. I look to get many years use out of this steel box. The quality and durability is exceptional!
