Zawiasa 3-częściowa 20 Hinge Yellow Zinc Steel Security Pin Anti-Tamper 135kg

Product Overview

The Zawiasa 3-częściowa 20 hinge with security feature is a three-part steel door hinge intended for heavy-duty interior and industrial applications. Its yellow zinc coating provides additional corrosion protection, making it suitable for environments where durability is required and moisture exposure may occur. Supporting a load of up to 135 kg for three hinges per door, it addresses the needs of commercial buyers specifying robust hardware for heavy doors.

A key differentiator is the inclusion of a security pin mechanism, which prevents hinge disassembly and enhances door safety. This reduces the risk of unauthorized access or tampering, making it particularly useful for facilities requiring enhanced security, such as warehouses, utility enclosures, or restricted-access commercial premises. Recommended for bulk procurement in industrial and commercial construction projects where high-strength and anti-tamper hardware is essential.
