When you need a high level of security for your fence line, you also need a security gate that can provide the same level of protection. The LockMaster S3 gate is designed to complement the Securus S3 fence line, and is available in both single and double leaf options. The welded steel wire mesh of Securus provides reliable defense for critical infrastructure such as government buildings, data centers, airports, and other secure units. The LockMaster S3 gate is equipped with adjustable anti-lift-off hinges, an anti-drill dead lock that can be accessed from both sides, steel drop bolts, and an anti-lever frame design to offer maximum security even in the most targeted locations.

Certified to LPS 1175 S3 accreditation, LockMaster S3 gates are engineered to withstand sophisticated attacks from mechanical tools and are ideal for high-risk sites that require compliance with global security standards.
