How to make a bend in a cable tray in a basement
Here's how to create a seamless rolling 90-degree bend in cable tray! 🛠️ This guide walks you through each step, from marking and cutting to forming and joining. First, marking is important📏. The space between your lines will be determined by the tray size. Since the jaws of the bolt cutter drags a layer of zinc across the cut end and forms a protective layer. Construction of a flat 90° bend (A) The amount of tray lip to be removed is equal to 2, 3/4 the width of the tray, half of this measurement will be removed on either side of the centre line.
