Professional Lockable Electrical Enclosures

CHNRH offers multiple lock types including cam locks for basic security, key-lock handles for frequent access, T-handle locks for easy operation, and deadbolt systems for maximum security. We also provide 3-point locking mechanisms for heavy-duty applications requiring water-tight sealing and enhanced protection.

For marine environments, 316L stainless steel is recommended due to its superior resistance to chlorides and salt water corrosion. While 304 stainless steel offers good general corrosion resistance, 316L provides enhanced protection against pitting and crevice corrosion common in offshore and coastal installations.

Yes, CHNRH specializes in custom lockable enclosure solutions. We can modify lock placement, provide multiple locking points, integrate combination locks, or develop specialized security features based on your specific requirements. Our engineering team works closely with clients to design optimal security solutions.

Our lockable enclosures are available in IP65, IP66, and IP67 ratings, corresponding to NEMA 3R, 4, 4X, and 6P classifications. The specific rating depends on gasket design, lock integration, and sealing methods. We ensure that adding locks does not compromise the protective rating of the enclosure.

CHNRH maintains ISO9001 quality management, ISO14001 environmental management, and ISO45001 occupational health and safety certifications. Our products are 3C, CQC, RoHS, and CE compliant, ensuring international market acceptance and adherence to global safety standards.
