[Shepherd, Matthew]

This foam or similar will also be needed for the “cribbing” that is used to trap the bar box from the sides and top.  You can look at the existing pieces to get an idea of what we did.

In the last photo, you can see we had a bid lower padding for this section. However,  6 of 8 boxes that we will transport this time are upside down, with the higher part of the wedge section sticking down.
