The Wire Girder – Double is designed to quickly and accurately position wire mesh in large slabon-grade applications. The girder is available in heights from 3″ to 9″ in 1″ increments and in lengths up to 40′. Optional snap-on sand plates are available for use on sandy soils to prevent the girder from turning during concrete placement. When using on a firm casting bed, the snapon plates are not a necessity but will give better support on slabs exceeding 6″ in thickness.
The optional snap-on plates are field installed by simply squeezing the bottom runners of the girder inward until they slip inside the plate tabs. Release of the runners will let them slide under the tabs and be held firmly in place by the tabs.
