The toughest environments call for the toughest products. Extreme Environment Tags from Master Lock deliver long-lasting performance - indoors and out.

Made from rugged industrial-grade polypropylene, Extreme Environment Tags are designed to withstand the most demanding conditions. Dust and dirt. High humidity. UV radiation. Harsh chemicals. Frequent washdowns. Extreme temeratures. You name it.

Throughout it all, these tags remain usable and easy to read. Our patent-pending process permanently fuses the graphics into the tag. Choose from a wide selection of standard lockout tags, or create your own design - from simple text to complex graphics. You can even enhance your lockout program with durable photo ID lockout tags for each employee.
