Preformed channels form a multi-tier trapeze rack secured with two-hole ninety-degree anti-rotation corners and supported by double preformed channel posts anchored into a concrete slab with post bases. Conduit clamps secure runs of conduit along each horizontal channel member. An adjustable brace connects via two-hole angular fittings to provide lateral stability to the frame. A one-inch layer of non-shrink grout is applied typically beneath the base plates.
