Duct spacers are designed to temporarily support an array of ducts within a trench until it can be filled with grout or similar suitable fill material. They also maintain accurate duct separation and alignment, which promotes reduced pulling tension. The spacer provides for independent support and separation of each duct. Ample openings for concrete flow is part of the spacer’s modular design. Formex®’s flexible design allows you to use less trench space and grout. Optional foot pads assure specified vertical separation between the trench floor and the bottom of the first duct tier.
