Bends are made by systematically assembling 15º segmental units and attaching them with pull-rings one-part, quick connect pull-rings one-part or joint section pull-rings one-part.

The formation of 90º bends using segmental units provides total spatial flexibility as these sections may be formed in multiple angles of 15º. As segments may be rotated with respect to one another, 3-dimensional 90º bends may be formed as well as simple, bends along a single plane.

Assembly is quick and easy. Once fitted, the 90º bend is robust, with excellent, smooth interior surfaces, making it ideal for use in air conduits and powder collection installations as well as for pneumatic material transport.
