Use a minimum of 2 nails here going into the beams. Measure the distance from the underside of the roof sheathing at the one third marks on the gable end rafters to the tops of the corresponding strongbacks below. Strongbacks can be altered to allow hvac installations as long as three 3 consecutive joists are attached. Strongback bridging is an excellent and inexpensive way to improve the overall rigidity of the floor system and eliminate vibration.

The same general concept may be used to reinforce staircases by attaching the strongback bracing to the stringers on the staircase making it possible for the structure to remain stable even when subjected to stress that would normally cause the stringers to fail. The drywall can be patched later. With this application the strongback joist works in conjunction with the beam to help keep floors and ceilings level even if the support or weight bearing beam should begin to deteriorate over time. Support each side with a temporary false wall.

These nails do not go through the base plate of the clip they go through the small extension plate the diagonal beam actually sits in.
