Hose & Seal-Offs
Hose Assembly
Ultra-Light birds are unique to DCD. They are made out of polyurethane and, as the name implies, are about half the weight of the regular Line Darts. The cones are very tough yet extremely thin – so thin, in fact, that they can be easily inverted in the event that the dart gets stuck and it is necessary to pull them back out.
Seal-Offs
Also known in the industry as a Triple Shuttle, this device is intended to be blown through a duct with compressed air and pull tape or rope which is attached to the rear eye of the dart. Similar to the line darts and ultralight birds, the fabric is flexible, allowing it to flex when going around bends.
It consists of three synthetic fabric parachutes attached to our tried and tested flexible fiberglass rod. The use of three parachutes provides the best reliability in catching air and pulling the tape down the conduit.
