Guide accessories

12 Guide accessories
T This section contains some recommendations based on our experience about the selection of guide accessories for the inspection in tubes and ducts.
As all pipes and chimney systems are different, the user has to decide about the guide accessory in every single case. For the selection of the correct tool it is important to consider that the guide accessory has to facilitate the introduction and the extraction of the camera head, as well as an adequate guidance. The danger of jamming or getting stuck in the tube has to be avoided.
