Compound fenestration assembly mull joints, compound fenestration assemblies using those mull joints, and methods of making and using the same are described herein. The mull joints in compound fenestration assemblies as described herein use universal joining strips to form both sides of a mull joint, as well as other universal components such as, e.g., corner gussets, locator plates, end plugs, seal members, etc. that may be used as needed to form mull joints as required in a compound fenestration assembly.

One or more embodiments includes a door assembly with a door jamb and a door header. A connection system is provided that directs the weight of the door header directly into the door jamb. Load on the fasteners is reduced by the connection system along with the potential for slippage for the door header after installation.
