Light gauge ducting systems
Jet caps are standard spot-welded and consist of 2 cones that are seamed together, internally provided with inner cone with a drain for rainwater (rigid copper pipe).
The outlet side is provided with a bird screen.
Because of the vertical outlet there is less resistance and the inner cone creates a higher outflow than with a rain cap.
Rolled sheets stitch-welded and spot-welded, with a 6 mm edge for lock rings.
