Spacers, plates and posts are additional construction and support elements that are modular in nature and allow the operating surgeon great flexibility when constructing hybrid ESF or circular ESF frames.

Mounts to ring to support additional wires, half-pins, and other elements.

 Allows frame construction with different diameter rings, mounting hinges “outboard” off ring surface, or elongation of partial ring assemblies. Also valuable with free-form frame construction.

Couples with 40mm hex bolt to provide rapid, accurate assembly of ring blocks
