1. A method of installing a coupling for joining pipe elements in end to end relation, said coupling comprising:
first and second segments attached to one another end to end surrounding a central space for receiving said pipe elements, each said segment comprising a first lug extending from a first end thereof and a second lug extending from a second end thereof, said first and second lugs of said first segment aligning respectively with said first and second lugs of said second segment;
a first adjustable fastener extending between said first lugs and a second adjustable fastener extending between said second lugs;
a first action surface positioned between said central space and said first lug, and a first stop surface positioned on said first lug, said first fastener being positioned between said first action surface and said first stop surface;
a second action surface positioned between said central space and said second lug, and a second stop surface positioned on said second lug, said second fastener being positioned between said second action surface and said second stop surface;
said method comprising:
with said coupling in a factory assembled configuration in which said first and second segments of said coupling are in spaced apart relation at a distance from one another sufficient to permit said pipe elements to be inserted while said segments are coupled via said first and second adjustable fasteners, tightening said first adjustable fastener until said first stop surfaces contact one another; and thereafter
tightening said second adjustable fastener until said second stop surfaces contact one another.
