What this lockout padlock is and who it fits

A red steel padlock with a 5/16 in boron alloy shackle and a laminated weather-tough cover. Keyed different so each lock opens only with its own key. Designed for outdoor lockout procedures where colour coding and corrosion resistance matter.

What to check on your existing setup before ordering

Verify the shackle diameter and height suit your hasp or lockout point. Confirm the 1 1/8 in vertical clearance fits the equipment you are isolating. Ensure the red colour matches your site colour-coding scheme.

How it behaves under sustained load rather than

The laminated steel body and boron alloy shackle resist cutting and prying during extended lockout periods. Weather-tough cover protects the mechanism from rain, dust and temperature swings. Non-removable key design prevents accidental key loss while the lock remains engaged.

Questions about this item

What comes with the 6121RED lockout padlock and what must be purchased separately?

The padlock is supplied as a single unit with its boron-alloy shackle and laminated steel body. No keys are included because the lock is keyed different; each lock requires its own key or a compatible keying system ordered separately.

How do I decide between the available versions of the 6121RED?

This model is offered only in red with a 1 1/8 in shackle height and keyed-different configuration. Choose it when you need a distinct colour code and unique keying for each lockout point.

What does the 1 1/8 in shackle clearance mean when the padlock is installed on a hasp?

The 1 1/8 in vertical clearance lets the shackle pass through standard hasp eyes and lockout devices while leaving enough room to close the shackle fully and engage the locking mechanism.
