Support bar for tubo shelving – reinforcement and securing of the shelving structure. The support bar in a tubo shelving unit is used to stabilize and reinforce the shelf legs, especially in layouts with few shelves or when combining multiple shelf bays. It ensures that the construction remains stable and stands securely, even under heavier loads or in open-shelf configurations. Additionally, the support bar can be used as a support for the goods themselves – either mounted at the rear edge of the shelf to prevent items from sliding backwards, or at the side to create a barrier and keep products in place.
