Hvac without Spot Welding Galvanized Steel Flexible Duct Connect Start Collar Ties
The round duct connector, also called the start collar and joiner, is made of galvanized steel plate. It can be directly connected to a round pipe or a square supply/return air box. Generally the semi-finished product will be provided. It means that you have to spot weld by yourself. By this way the volume of the product can be smaller, which will reduce transportation costs. Available in sizes from 150D to 650D.
