Security Lockout Padlock

The Master Lock 1803LHBLK is a steel lockout padlock designed for safety procedures that require individual key control. Its keyed-different configuration ensures each lock opens only with its own key, supporting strict access management in industrial or commercial environments.

Verify Shackle Fit Before Ordering

Confirm the 5/16 inch shackle diameter and 3/4 inch horizontal clearance match the hasp or isolation point on your equipment. The extended shackle provides 2 inches of vertical clearance, so measure the available space to ensure the lock body and shackle can engage fully without obstruction.

Integrates With Lockout Stations

The black steel body resists prying and fits standard lockout stations or group lock boxes. The non-removable key feature prevents keys from being left in the lock, reinforcing procedure compliance. Hardened steel shackle material withstands cutting attempts while the bumper protects finished surfaces during use.

Questions about this item

What is included with the Master Lock 1803LHBLK padlock and does it require any separate components?

The padlock is a complete, self-contained mechanical push-button lock with a steel body, hardened-steel extended shackle and standard key; no additional parts are needed for operation.

How do I decide between the available versions or capacities for this lockout padlock?

This model is offered as a single configuration — keyed different with a 2-inch extended shackle and black steel body — so there are no alternative versions or capacities to choose from.

What does the 2-inch shackle height mean when the padlock is installed on a real hasp or chain?

The 2-inch shackle height provides 2 inches of vertical clearance and 3/4 inch of horizontal clearance, allowing the lock to fit over thick hasps, chains or multiple lockout points while the 5/16-inch hardened-steel shackle resists cutting.
