K08A00A Vertical Clamp Connector (VI-SO)

The VISO 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.

  • The grip and force exerted by the clamp arm (Piece 20) is variable by rotating the drive stud (Piece 30.) Max load on the hex drive is 50 ft/lb.
  • STRENGTH RATINGS:
    Minimum failure load for one VI-SO
    • 120,000 LB. - Transverse Shear
    • 65,000 LB. - Longitudinal Shear
    • 460,000 LB. - Compression
    • 65,000 LB. - Tension (Corner Fitting Limit)
  • Maximum Yield Load
    • 44,000 LB. - Restraint Against Upward Force
    • 75,000 LB. - Transverse Shear
    • 50,000 LB. - Longitudinal Shear
    • 280,000 LB. - Compression
  • Two grease fittings allow for easy lubrication. Recommended Grease: Red Lithium High Temperature.
  • Dimensions without tolerance are subject to manufacturing tolerances.
Product Notes
  • If using as a lifting product, proof testing is required. Must be used in pairs and rigidly held.
    WLL 15,000 LB. Design Category A
    WLL 10,000 LB. Design Category B
  • Use for a slack-free, clamp-down connection of ISO 668 type container or similar structure. Connector enters the large bottom aperture of the standard corner fitting (ISO 1161) & clamps down on the inside of the bottom wall.
  • Use to tightly secure containers to structures such as special pallets, ships' deck, overhead beams, foundations, chassis or other containers.
  • While this standard VI-SO is not designed for single wheels or lifting, products for these purposes are available.
  • Locate connectors per "male fitting instructions" on Tandemloc Data Sheet DF-72047-16 (Sheet 2) for standard sized structures.

VI-SO grips the corner tightly, in contrast to other commonly used twist locking connectors which have approximately 1/4" of "play".

Use also to connect other items to a container such as antenna, air conditioners, davits or railings.

Use - for a slack-free, clamp-down connection of each corner of an ISO 668 type container to a deck or other structure, lower the container so that the open connector enters the large bottom aperture of each ISO 1161 standard corner fitting. The clamp arm bears down on the inside of the bottom wall when the drive stud is screwed in.

Use cap screws and lock nuts to assemble the connector to a suitable receiving structure. Locate connectors per "male fitting instructions" on Tandemloc Data Sheet DF-72047-16 (Sheet 2) for standard sized structures. For non-standard sizes use the principles implied on this sheet to determine your location. We would recommend torque to be in the range of 30-50 ft/lb., and that blue or red Loctite be applied to the threads to avoid vibration loosening. If this installation is on board a ship, we recommend tightening to the high end of the range. For land based installations, the low end.

The VI-SO is to be bolted to the desired structure using four 3/4" SAE Grade 8 steel cap screws. Special flat head cap screws and locknuts are available with hex socket and slotted end. This permits the cap screw to be held from the threaded end while turning the lock nut (useful when the head end is not accessible).

To secure an ISO container or similar structure first open the connector fully by turning the drive stud counterclockwise until it is within (Sheet 1) dimension. 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.
