Reinforcement spacer and support
A reinforcement spacer and support for spacing and supporting reinforcement bar or mesh a fixed distance from a surface, the spacer including: an elongate element having three parallel edges A, B and C extending about a central axis, wherein each edge is capable of defining a reinforcement support edge in one orientation about the central axis, or a part of an opposing base surface in another orientation about the central axis. The spacing distance between at least two pairs of the parallel edges is different, such that in one orientation about the central axis the perpendicular distance between a first of said edges and the opposing base defines a first predetermined height H1, and in another orientation about the central axis, the perpendicular distance between a second of said edges and the opposing base defines a second predetermined height H2. The parallel edges A, B and C are interconnected by a web structure, the web structure further defining a series of passages that pass through the central axis that are configured to allow concrete flow there through. Optionally, the spacer may include end formations that align with the central axis to enable end to end connection of like spacers. Figure 1 4 4 x x Hi x 12 7 Figure 2 Figure 3 5 ~x_
