Flextron 36 Inch Long Restraining Cable for Use with Food Service Gas Connector. Using the cable for movable gas appliances extends the service life of the gas connector, by avoiding stress on the connector by unexpected forces. Prevent damage to your gas hose connectors while ensuring a safe working environment with this Equipment Restraining Cable. The cable itself is only 36" long, which eliminates the possibility of your 48" gas connector hose from being accidentally disconnected from the appliance. The ANSI Z21.69 Standard, section 1.7.4, states that any caster mounted equipment should be installed with a restraining device like this one. Heavy-duty mounting hardware and spring-loaded hooks are included.
