Abstract
Abstract A mounting apparatus including a mounting bracket, for attachment of an open web structural support to an end support such as a support wall enables the upper chord member of the structural support to be mounted flush to the top of a bearing plate on the top of the support wall. The bracket is comprised of an angled plate member which is securable to the bearing plate and includes a chord receiving portion having outwardly extending channel members which receive opposite side edges of the ends of the upper chord member. Adjustable length end web members are connected to the angled plate member to accommodate a change of length of the structural support. An adjustable spacer apparatus is provided in the channel members between the end of the upper chord member and angled plate member for accommodating structural supports of different lengths.
