Would someone kindly let me know the formula to create a flat 45 in say 100 mm cable tray for example. So I can then use the formula on different cable tray sizes and to different angles. the cable tray is 3 metres in length, this doesnt matter but i think the width does. each bend is a 45 degree angle. but the length of the part in the centre is the concern as i have seen different. The method for producing bridge bend elbows is as follows: Take a 90-degree cable tray bend elbow as an example, and apply the same principles for 45-degree bends accordingly. The length of the bottom side (bottom diagonal) after bending the cable tray should be equal to the width of the cable.
