3 . The swivel joint of claim 2 , wherein said second cylindrical member comprising a ridge formed in said outer surface thereof and parallel to said plane perpendicular to said central longitudinal axis and wherein said end of said first cylindrical member abuts said ridge.
4 . The swivel joint of claim 1 , wherein first cylindrical member comprising a second groove formed in an outer surface thereof and parallel to said plane perpendicular to said central longitudinal axis.
5 . The swivel joint of claim 1 , wherein said first and second cylindrical members include a plurality of equally spaced orifices located adjacent end portions of said swivel joint and along said plane perpendicular to said central longitudinal axis.
6 . A chimney shield system, comprising:
a first cylindrical shield member;
a second cylindrical shield member; and
a swivel joint, comprising:
a first cylindrical member;
a second cylindrical member rotatably coupled to said first cylindrical member, said first and second cylindrical members extending along a central longitudinal axis, wherein said first and second cylindrical members rotate independently of one another about a plane perpendicular to said central longitudinal axis, said swivel joint configured to couple said first and second cylindrical members together.
7 . The chimney system of claim 7 , wherein each of said first and second cylindrical members comprise a groove formed in an outer surface thereof, located adjacent an end thereof, and parallel to said plane perpendicular to said central longitudinal axis, said groove of said first cylindrical member overlapping said groove of said second cylindrical member.
