Lockout Padlock for Safety Procedures

The Master Lock S31PRP is a thermoplastic lockout padlock designed for industrial safety programmes. Its purple body and stainless-steel shackle identify energy-isolation points during maintenance. The key-retaining mechanism prevents the key from being removed while the shackle is open.

Keyed-Different Cylinder

Each padlock ships with a unique key cut so that no two locks in a set share the same code. This ensures only the authorised holder can remove their personal lock from a group lockout hasp. The non-removable key feature reinforces accountability during shift changes.

Corrosion-Resistant Under Continuous Exposure

The thermoplastic body and stainless-steel shackle resist moisture, chemicals and UV exposure in plant environments. The key-retaining action stays reliable after repeated daily cycles. Labels included with the lock remain legible through wash-downs and outdoor weathering.

Questions about this item

How does the 3/16 in shackle diameter perform when fitted to a standard lockout hasp?

The 3/16 in stainless steel shackle fits typical lockout hasp holes and provides corrosion resistant strength for industrial lockout tagout procedures.

What does the key retaining feature mean for daily use?

The key cannot be removed while the padlock is open, so the key stays with the authorised user until the lock is secured again.

Will the 1 7/8 in high thermoplastic body fit inside a crowded electrical panel?

The compact 1 7/8 in body height and 1 3/8 in width allow it to sit in tight panel spaces alongside other lockout devices.
