The support is very stable, it will not slide or tip and has excellent load carryingcapacity. It is easy to install and can be bent around voids and/or GIRDER DOUBLE The Wire Girder Double is designed to quickly and accurately position wire mesh in large slab-on-grade applications. The girder is available in heights from 3" to 9" in 1" increments and inlengths up to 40'.

4 Optional snap-on sand plates are available for use on sandy soils to preventthe girder from turning during concrete placement. When using on a firm casting bed, the snap-on plates are not a necessity but will give better support on slabs exceeding 6" in optional snap-on plates are field installed by simply squeezing the bottom runners of thegirder inward until they slip inside the plate tabs. Release of the runners will let them slideunder the tabs and be held firmly in place by the Order Specify: quantity, type, height & Order Optional Snap-On Plate, Specify: quantity and Bar Support9 MeadowBurke Plastic Reinforcing Bar PLUS SB SLAB BOLSTERThe Tuff Plus SB is a composite slab bolster that is used to provide accurate cover for lower matsof steel reinforcement in concrete elements.
