A bracket useful for seismic bracing of conduits is described. The bracket is placeable over a threaded rod and includes sidewalls for accepting a fastener and a pair of apertures for attaching to a brace. Certain brackets are stackable, allowing for the attachment of multiple braces from a single anchored rod. Other brackets include two parts that allow the bracket to be assembled about a threaded rod without removing elements which might previously be attached to the rod.
