This detail shows the connection of a hot rolled interior column to a cold rolled rafter at an end-wall. The roof purlin also shown in the detail is just shown for orientation.

The clip that is pre-welded to the rafter should be placed on the outside of the column web. This clip is typically slotted to allow for rafter deflection at the column (not shown in the animation). A flat washer needs to be installed on the slotted side of the clip with the bolt.

What you will need:

• (2) 5/8” A325 Structural Bolts and Nuts (typically black)
• (2)1/2” Washers

Tip:
1. The column should be placed prior to the roof rafter being raised

2. Based on anchor bolt accuracy it may make sense to install the rafter with the clip on the inside of the column. This will effectively move the column ¼” towards the peak of the roof. This should only be done if the corner columns are perfectly plumb.
