Also known as an Internal Frame, an Mounting Mesh provides support mounts for heavier parts that cannot be fitted to the Endoskeletal chassis of a Maverick Frame or Movable Frame based unit.

The internal frame wraps about the internal components and mounts at specific points with the Endoskeletal chassis. Parts not mounted onto the IS are instead mounted onto the Mounting Mesh on plug sockets or are held in unique locker configurations (not unlike sliding various parts of an engine together).

The Mounting Mesh is able to expand and contract dramatically and is considerably more durable than the Endoskeletal chassis or Interface Hive. The form is also able to take a number of different shapes and forms. Practical examples include producing a physical shield on an arm or a blade in combat or smoothening the body. While transformed, the internal mesh will act as one large aeroelastic control surface. These changes alter the Armored Mesh which is layered over it.
