ABSTRACT:
A joist bridge has a web extending between a pair of end members. The web has a straight edge and an edge having a central indentation. The indentation provides a space through which plumbing pipes, electrical conduits and wiring and the like can be run. The joist bridge is economical of material and is therefore relatively inexpensive to manufacture. An adhesive strip may be provided along the top of the joist bridge to bond the joist bridge to the flooring above.
