Steel wire Duct chairs (Bar Chairs) are widely used to support the ducting which cross both direction of a PT slab. Kingflex supplied Duct Chairs are suitable for both the 70mm and 90mm flat ducting. The sizes range from 25mm, 30mm and in 10mm increments up to 480mm. Special orders can be made to go as high as the design requirements are.

The bar chairs Kingflex supply can be easily clipped on/ tied-on to the duct depending on site conditions and requirements. The feet of the bar chairs are plastic coated to prevent corrosion. To ensure maximise concrete cover, the chairs are approximately 2-5mm above the ducting.
