ABSTRACT:
A spacer device for use in supporting bar-like members in construction applications, the device including a body having a plate portion with a support post portion having a saddle configured on the upper edge thereof, with a plurality of legs affixed to the plate member and extending generally perpendicular thereto. The support post is provided with either an aperture for passing fastening wire therethrough for securing the bar or a pair of aligned openings for receiving a U-shaped clamp member. The plate portion is provided with recesses in alignment with the legs to permit stacking of one spacer atop the other for building layers of rebar framework. The legs may be removable for reverse connection, thus permitting the plate portion to be used as a "sand plate" support for reinforced concrete construction, or alternatively a separate "sand plate" may be used. The plate portions may be secured to strapping at predetermined spacing for facilitating the use thereof, and separate rod members may be attached for maintaining lateral spacing.
