Abstract: A support bracket for holding, securing and portioning orthopedic tools and/or devices within a case or tray is described. Multiple support brackets creating a modular system of brackets may be used within the case. Each support bracket is designed to releasably lock within an opening of a floor of the tray or case. The support bracket comprises a support member having opposing sidewall surfaces that upwardly extend from a base portion. A bracket insert, having a bottom wall extending distally from a sidewall, is positionable within a passageway formed within a bottom surface of the base portion to thereby lock the support bracket in position within the tray.
