Hello, 

After receiving the G&R parts yesterday, Dario checked the dimensions and hole placement on all parts and found that one hole on the I-Beam for the RICH trolley brackets is ~1 inch away from its correct location. 

DSG has also verified that the hole is not in the correct location with respect to the drawing. 

A picture of the incorrect hole with its correct location on the I-Beam marked is attached. Also attached is the parts drawing in a pdf with page 6 showing the misplaced hole circled in red. 

Because this part is not needed until RICH is almost ready to go to Hall B, Marc will contact G&R to be able to return this part in order to have a new hole drilled. 

Best regards, 
Tyler
