Manufactured with soft ends with hooks one end and D rings the other end complete with cuff to go into next section. This provides a more efficient system with less air leakage and faster installation.
The vent tubing is manufactured with spring steel rings at each end. The ring end of one tube is inserted into the ring end of the next length of tubing being installed. The rings are then pulled back leaving 3" between rings for installation of the Multi-Clips. Recommended spacing of Multi-Clips is 20" to 24" around perimeter of tubing (ie) - 6 multi-clips for 42" to 48" diameter tubing.
