The heavy duty intersection chair was designed for the precast industry and the production of "Super T Beams". The result is a design that takes advantage of the intersection to provide a chair that does not move. Clipped to both bars at the intersection, the chair is amazingly secure and will not swivel or turn. Ideal in vertical applications. The chairs are currently designed to accommodate combinations of Y16 bars and Y12 bars. Designed and manufactured from quality plastic for optimum performance, the chairs have been load tested to exceed 200kg.
