The Rugged Zenex™ Thermoplastic Housing Stores unused cable, making the device more manageable – whether in use or in storage. When the control lever is closed, tension on the cable can only be increased. Internal ratcheting mechanism allows users to add tension, even after safety padlocks have been applied. Opening the control lever releases the lockout. With the control lever open, pressing the cable release button releases the cable after the lockout is complete
