Master Lock 6121 Yellow Steel Padlock

The Master Lock 6121 is a laminated steel padlock with a yellow weather-tough cover and a boron alloy shackle. It is keyed alike for users who need multiple locks operated by a single key. This lock suits industrial lockout programmes and outdoor security points where colour-coded identification is required.

Check shackle dimensions

Verify that the 5/16 inch shackle diameter and 7/8 inch width across the shackle fit your hasp or chain link. Confirm the 1 1/8 inch shackle height clears the attachment point. Ensure your facility uses the same keyed alike code so this unit matches existing locks.

Steel body and boron shackle resist prolonged

The laminated steel body with yellow coating and the boron alloy shackle are built for weather tough performance in sustained outdoor conditions. The non-removable key design keeps the key retained during extended lockout periods. Materials are chosen to maintain function through repeated daily cycles without degradation.
