A method of installing a coupling for joining pipe elements uses a pipe coupling having two segments with action surfaces in facing relationship. Attachment elements on each segment, in the form of lugs, accommodate adjustable fasteners which draw the segments together when tightened. Support surfaces on the lugs engage one another and react the fastener force. Stop surfaces are positioned on the lugs adjacent to the support surfaces. Engagement between the stop surfaces provides a visual indication that the coupling has been properly installed.

Support surfaces on the lugs engage one another to visually indicate that a proper installation of the coupling has been achieved.

Coupling having visual installation indicators

A pipe coupling has two segments with angularly oriented action surfaces in facing relationship. The action surfaces induce relative rotation between the segments when the segments are drawn together to engage the pipe elements being joined. Attachment elements on each segment, in the form of lugs, accommodate adjustable fasteners which draw the segments together when tightened. Angularly oriented support surfaces on the lugs engage one another and react the fastener force. Stop surfaces are positioned on the lugs adjacent to the support surfaces. Engagement between the stop surfaces limits the relative rotation between the segments.
