Step 40: Attach TNR Brace
A: With a helper, hold the Narrow Wall Frame in place as shown in fig.40.1. Place (401) TNR Brace Support so
that it connects the Rock Wall Frame and the Narrow Wall Frame, making sure that the outside bolt holes are at
the bottom. Attach to each frame using 1 (H13) Hex bolt.
Do not attach Narrow Wall Frame to the Fort.
