1. The connector fits ISO 1161 Corner Fitting large aperture and incorporates a clamping action that removes any slack between the corner fitting and the body of the connector. Use whenever a slack-free connection is preferred. Hot-dipped galvanized for rugged use.

2.The grip and force exerted by the clamp arm  is variable by rotating the drive stud 。 Max load on the hex drive is 50 ft/lb., making approximately 2,000lbs of clamp force.

3.To secure an ISO container or similar structure first open the connector fully by turning the drive stud counterclockwise until it is withindimension. Lower container so that the upward projecting portions of the connector enter the large apertures in the bases of the corner fittings. Turn the drive stud clockwise to secure. 50 FT/LB. of torque in the drive stud when metal to metal contact is achieved is recommended. Excessive torque pre-loads the clamp arm, resulting in a reduction of its maximum strength.
