A support member for supporting a roof of a subsurface space. The support member may include a base portion for defining a surface area to contact a ceiling of the subsurface space. One or more sockets may extend from the base for defining openings for receiving roof bolts therethrough. Accordingly, the support member may be configured to function as a washer for the roof bolts to support the roof material above the ceiling. The sockets may include covers for preventing the roof bolts from extending out of the sockets. The sockets may be oriented at angles with respect to the base such that when roof bolts are placed in the sockets, the roof bolts may extend at angles with respect to each other in a splayed configuration.
