MASTER LOCK S31 Zenex Thermoplastic Safety Padlock

The Master Lock S31 Zenex™ Thermoplastic Safety Padlock is designed specifically for Lockout/Tagout (LOTO) applications. Featuring a lightweight yet highly durable thermoplastic body, this padlock is built to withstand harsh industrial environments, offering excellent resistance to chemicals, UV rays, and extreme temperatures.

Equipped with a Marine Grade 316 stainless steel shackle, the S31 provides superior corrosion resistance, making it ideal for use in demanding or corrosive settings. To prevent accidental security lapses, the padlock features a key-retaining cylinder, which ensures the padlock cannot be left unlocked as the key can only be removed when the shackle is closed.
