Abstract
A track switch snow melter duct connection system including end flanges with a top portion, each end flange being attached to a distal end portion on a duct which is to be connected such that the top portion extends outward and above the distal end portion. Side flanges are also attached to each duct and extend outward such that a gap exists between the distal end portion of each duct and the side flange. The connection system also includes an attachment mechanism for attaching the top portion of end flanges on adjacent ducts and a connecting member which can be slidably inserted between adjacent ducts having an elongate channel shape formed by a base and two side legs and two extensions extending from and attached to the distal end of the two side legs. The connecting member has a width such that two connected end flanges can be positioned between the two side legs and such that the extensions are positioned in the gap between the side flanges and distal end portion of each duct.
