Master Lock Co 5480D Portable Combination Lock Box

Product Description

The MASTER LOCK CO 5480D is a portable combination lock box designed for keyless key storage and access control in outdoor and commercial applications. The unit features a fully removable shackle that allows over-the-knob installation, a 4-digit numeric combination dial that can be set by the user, and a shutter door that shields the dials from weather, dirt, and grime. The molded body and vinyl-coated shackle help prevent surface scratching on doors and hardware. This lock box is suited for field service professionals, real estate agents, and property managers who need secure, repeatable key access without a physical key.

The 5480D is built for outdoor use and performs well in access control applications including real estate lockouts, security gates, and fencing installations. The over-the-knob removable shackle design makes temporary or semi-permanent installation straightforward. The user-settable combination eliminates the need for key management and provides an auditable access point for properties with rotating service personnel. Units are sold in packages of 4, making this a practical choice for contractors or property management firms managing multiple sites.
