Coupling joint for tubular perpendicular elements - has grooved sockets tightened by single bolt to fix elements at required angles

摘要

The coupling joing consists of two separate elements which are joined together by a through nut and bolt (BU). Each half element has three grooves perpendicular to each other and having a sq. or circular section to take the perpendicular members (BA). The gap left in the elements is small enough to allow gripping the tubes when the bolt is tightened. The connector allows angles other than 90 deg. to be provided between the elements.
