Home / What size cut should be made at a 90-degree bend in a cable tray

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. If fabricating, mark the side rail at intervals based on the calculated arc length, cut V-notches, and bend the tray until the gap closes. The formula is: 90-degree bend: BD = 2 × Radius × (1 – cos (Angle/2)) 45-degree bend: BD = 2 × Radius × (1 – cos (45°)) The length of a 90-degree bend can be calculated using the bend radius and some other values. By applying the following formula you can quickly find the size of cut out section that you need to cut out of the side of the cable tray, or gutter-type section to make that angle. (A) = cable tray width (600mm) and B = Size of angle (22°) First you have to find (C) which is found by dividing 90°.
