Abstract

A connector for joining a supported member to a supporting member is formed with a series of angularly-joined flanges. The flanges are substantially planar and are substantially vertically oriented, when joining the supported member to the supporting member. The connector allows the end of a supported truss to be connected to a vertical member in the open web of a supporting truss.
