Combining strength with cutting-edge technology, this padlock is ideal for securing gates, fences, outbuildings, and industrial applications.

This smart padlock enables access via your smartphone using the free Master Lock Vault app. It eliminates the need for physical keys or remembering combinations, offering convenience, control, and a higher level of security for outdoor locking needs.

Constructed for durability, the 4401LHD features a boron carbide shackle for maximum cut resistance, a reinforced body, and a weather cover to shield electronics from harsh outdoor conditions. It is IP56-rated for water and dust protection.

Whether you manage multiple sites or need secure access to remote locations, the Master Lock 4401LHD provides an advanced locking system that adapts to modern facility management.

Ideal for commercial, industrial, or high-security domestic use, this smart padlock gives you total access control without the limitations of keys or shared codes.
