Safety padlock for lockout procedures

This Master Lock Zenex padlock is built for industrial safety lockout applications. The purple thermoplastic body measures 3 in height with a 3/4 in thickness and 1 1/2 in width. It features a metal open shackle with a 1/4 in diameter and 1 1/2 in clearance. The cylinder is reserved for safety use and the key is non-removable when unlocked.

Chemical resistance and thermal stability

The thermoplastic body resists chemicals and maintains integrity across a wide temperature range. With no moving parts exposed to corrosion, the lock operates quietly during application and removal. Power draw is not applicable for this mechanical device. The keyed-different mechanism ensures each padlock requires its own unique key for authorised access.

Sustained lockout reliability

Under continuous lockout conditions, the shackle and body retain their dimensions without deformation. The non-removable key feature prevents accidental unlocking while the padlock remains engaged. The keyed-different system supports multi-person lockout protocols where each worker controls their own lock. This padlock is not suited for high-security perimeter gates or applications requiring master-keyed access across large facilities.

Questions about this item

How do I install the 13/16 in shackle through my lockout point, and what step is often missed?

Insert the metal shackle through the hasp or chain link, then press the lock body down until the cylinder clicks; the non-removable key must stay in the lock while engaged, which is the step users forget.

What part of this purple Zenex padlock will need replacement first?

The 1/4 in diameter metal shackle is the wear item; repeated insertion and exposure to chemicals can deform or corrode it, while the thermoplastic body and safety cylinder are designed for longer service.

What limit appears first when this lock sees daily chemical exposure?

The shackle’s metal construction will show corrosion or pitting before the chemical-resistant thermoplastic body degrades, especially at the 13/16 in clearance points where fluid collects.
