T10021A-100 Aperture Plate

The Aperture Plate is a useful product for those projects that do not require the other apertures (side and end "holes") found on ISO corner fittings or the "box structure" that may get in the way or are otherwise not needed.

The Aperture Plate is weldable and compatible with the large selection of connectors and twistlock devices found on this website that ordinarily fit into the same opening found in the corner fitting. Tandemloc can also design and build your special product incorporating this aperture plate. Just let us know what you need!


  • Materials: Low-carbon steel suitable for welding.
  • Finish: Self-colored.
  • Weight: 9.3 LB.
  • Locate connectors per "female fitting instructions" on Tandemloc Data Sheet DF-72047-16 (Sheet 2) for standard-sized structures.
