LF Tender Text
METU Circular Flange LF: Sturdy circular flange designed to simplify the assembly of light-gauge round ducts and fittings with a turned-out edge. The flange is made of a profiled sheet metal stripe which has been precisely bent to form a ring and is characterized by a tapered groove (with injected sealant HD) which is snapped on the turned out edge of the duct or fitting. This connection does not create any projections inside the duct. The cone-shaped flanges are then connected together rapidly (only one nut must be tightened) thanks to a SR Joining Clip.
