The Mastsayf™ Flexible Cable System provides complete safety and security for workers who need to climb towers in the energy and utilities industry. The system offers hands free operation and absolute fall protection allowing users to ascend or descend completely unrestricted, providing freedom of movement and increased productivity.

“The Mastsayf™ sleeve, the connecting device that attaches to the front fall arrest D-ring of the users full body harness and the lifeline has a unique swivel that provides hands free operation whilst limiting free falls to a maximum of 600mm”, says Greg Peterson, Systems Manager for Capital Safety, Australia and New Zealand. “Should a user fall, the sleeve immediately locks down onto the systems cable and arrests the fall.”

The Mastsayf™ system has been designed for easy installation and is ideal for use as either a permanent or temporary climbing system. The Mastsayf™ system can be easily removed and re-installed on other towers as required. The systems’ versatile design makes installation to virtually any tower quick and easy.
