Abstract: A spacer assembly including a spacer with a body having a base portion with a generally centrally disposed support post portion, one end which is formed as a planar surface with a centrally located generally concave saddle portion configured for receiving a reinforcing bar, the planar surface being provided with apertures therethrough on both sides of the saddle. A clamp member is provided for simultaneously securing mutually perpendicular rebars to the chair, the clamp member including a generally U-shaped lower portion, with the depending arms thereof in spaced generally parallel relation for engaging a first bar within the saddle. A pair of generally identical hook arms extending upwardly from the bight portion, the hook arms being oriented for engaging a second rebar in an orientation perpendicular to a first rebar engaged within the saddle portion.

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.
