The extensive range of Circular Spacers are designed and manufactured from quality plastics, for strength and stability. The unique design offers accurate cover for 360 degrees. It will not twist when in position due to the in-built sleeves which adjust to hold the bar firmly. As the size of the bar increases, the cover remains the same. The Circular Spacers are concrete grey in colour and are designed to be connected to the fitment so that it is in a vertical position, enabling it to rotate when the formwork is assembled.
