What are the differences between cable trays?
Thread Content
In the cable trays, there are some whose meaning I’m not sure about. Vertical upper right elbow, vertical upper left elbow, vertical lower right elbow, vertical lower left elbow. What are the differences between these elbows? For example, what kind of elbow is used to go from 4 meters to 8 meters and to the left? I seek advice from experts! Thank you
From 4 meters up to 8 meters then to the left: first a vertical upward bend, then a vertical leftward upward bend. Each elbow structure is different, and when making a choice it is necessary to refer to the sample images.
