The Terrier TS Vertical Clamp is designed for vertical lifting and transporting of steel plates and structures. The straight design of the lifting shackle means this clamp is not appropriate for horizontal or sidelong loading. A safety mechanism and lock ensures the clamp stays closed and engaged during use. Each clamp has the lifting capacity and jaw opening clearly engraved on its body. Each clamp is made from quality steel components and is backed by great engineering and a 5 Year Warranty.
