ABSTRACT:
A pair of frame members are secured to the ends of a pair of ducts having a generally circular or arcuate configuration. Each frame member has the same generally circular or arcuate configuration and has an inner vertical wall and an outer vertical wall. The outer vertical wall is connected to a sloped rigidifying portion which extends outwardly from the inner vertical wall. Both the inner and outer vertical walls have horizontally extending flanges which are in abutting relation and their end portions are clampingly engaged. The frame members have a circumferential or peripheral dimension less than the circumferential or peripheral dimension of the duct member so that at least one gap is formed in the circular or arcuately shaped frame member. The frame members are positioned on the duct end portions by inserting the frame member flange portion inside the duct end portions with the top surface of the frame member upper flange abutting the underside of the duct. Fasteners secured to the duct end portion of the flange members are applied to the flange member and duct end portion to urge the frame member flange portion against the undersurface of the circular duct.
