Connecting piece with a "parallel" flange on one side designed to be welded on fittings so that they can be assembled to the METU-FORM system of ducts with SRX joining clips.
The available dimensions appear in the products names.
Please refer to the "Product and Prices" link on the right side.
The collars are not necessary for the "plain" system of ducts and fittings (they do not have flanges), as they can be assembled directly with MUX Overcollars.
