The ISS box used to be dogged down using CL5 dog clamps, and is now dogged down with CL2 dog clamps, with CL5 dog clamps installed up side down against the base.  One of the clamps installed against the base is a fork clamp, installed as the South fork clamp on the East side of the box, where the ISS box is up against the PMC box, so very difficult to access.  Images attached show each side of the box, and the file names identify which clamp(s) and which side. In the images, the first clamp identified is the North clamp East side, and from there the clamps are identified in a counter clockwise direction, ending with the South clamp East side (which is shown in the last two images).
