Product description
Ensure your four-post lift remains safe in the event of cable tension loss with the SVI BH-7531-75 Slack Cable Dog Assembly. This critical safety device is designed for Rotary SM180 series lifts and is engineered to automatically engage and stop the lift if a cable goes slack or fails. The assembly features a spring-loaded “dog” or pawl that remains in standby during normal operation but reacts instantly to emergency conditions.
