The metal body measures 2-7\/32 inches (56mm) wide, providing a durable housing for high-security deployments. The boron alloy shackle is 11\/32 inches (9mm) in diameter with 2 inches (51mm) of vertical clearance, offering strong resistance to cutting and sawing attacks. The lock connects via Bluetooth to the Master Lock Vault platform, allowing administrators to manage access permissions through a companion app or web interface. Licensed locksmiths, security integrators, and facility managers typically specify and install this hardware.\u003c\/p\u003e\n\u003cp\u003eThe 4401LHEC is suited for commercial facilities, multi-family properties, job sites, and institutional settings where tracked, keyless access is required. The Vault platform supports individual lock assignments and system-wide access control, making it appropriate for fleets of locks across a single property or multiple locations. Administrators can grant or revoke access remotely, and the app logs entry events for accountability purposes. It is also applicable for high-security residential use where traditional keyed padlocks are being replaced with managed electronic access.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e56mm wide metal body construction for impact and weather resistance\u003c\/li\u003e\n  \u003cli\u003eBoron alloy shackle with 11\/32 inch diameter resists cutting and sawing\u003c\/li\u003e\n  \u003cli\u003e2 inches of vertical shackle clearance for standard hasp and gate hardware\u003c\/li\u003e\n  \u003cli\u003eBluetooth connectivity integrates with the Master Lock Vault app and web console\u003c\/li\u003e\n  \u003cli\u003eMilitary-grade encryption protects against wireless interception and replay attacks\u003c\/li\u003e\n  \u003cli\u003eSupports both individual user access and administrator-controlled system-wide lock management\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe 4401LHEC is compatible with the Master Lock Vault access management system and is designed for use with the Master Lock Vault app and web interface for administrator and user access control.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed locksmith or security integrator familiar with electronic access control hardware.
