Strata10 stock a full range of Wire Bar Chairs to suit 70mm x 20mm metal duct. Bar chairs for 43mm and 90mm duct can be made to order.
The Wire Bar Chairs are available in either clip-on or tie-on style.
The Chairs are used to support ducts (wire cables), that criss-cross through concrete slabs. These ducts are sometimes set in a wave-like profile, and Strata10 supplies the chairs in many different heights to facilitate this. Our chairs are only 3-5mm above the duct to maximize concrete cover.
