Our unique elbow, called the Convert-A-bow, is a one-piece specialty elbow made with a B-style elbow that “converts” into an A-style opening at the crimped end of the elbow, allowing the user flexibility with applications that would require a B-style elbow but where an A-style would be preferred.  The Convert-A-Bow is made from .019 gauge aluminum.  All elbows come individually wrapped in polybags to help protect the elbows.
