Abstract
In one embodiment, an improved high-speed corner flange connection member is disclosed which includes creases or bends allowing the leg portions to be bent or angularly deflected away from such creases downwardly so as to form a bowed configuration. In some embodiments, the connection member includes clearance holes and tap holes which are strategically positioned such that when a pair of duct sections are positioned in end-to-end relationship for joinder, the opposed connection members are arranged such that a clearance hole is positioned in registration with a tap hole; other embodiments include similarly shaped openings which are associated with the respective opposed connection members; and in still other embodiments, a substantially flat corner element is constructed utilizing the strategically placed clearance and tap holes. A plurality of differently configured high-speed fastener members for substantially eliminating misalignment and cross-threading issues are also disclosed.
