The MASTER LOCK 5400D Combination Portable Lock Box is designed for secure key storage. It features a three and one-fourth inch wide metal body for durability. This lock box can be mounted over most doorknobs, and it allows users to set their own four-digit combination for keyless entry. The shutter door prevents weather and dirt from interfering with the combination dials, while the molded body makes it resilient against scratches.
