B-LINE 4A-18-CSF48 – Frequently Asked Questions

1) What is the B-Line 4A-18-CSF48 cable support fitting used for in a cable tray run?
The 4A-18-CSF48 is a cable support fitting for B-Line cable tray, sized for 18 inch tray width with a 48 inch radius and a 4 inch height (3 inch NEMA load depth). It is the piece that carries and supports cable through a curved section of the run rather than a straight length of tray.
2) Is this B-Line cable support fitting aluminum or steel?
Aluminum. That keeps the weight down for overhead runs and suits the same aluminum tray it is bolted into, which matters when you are avoiding mixing metals in a damp or corrosive area.
3) What height and load depth does the 4A-18-CSF48 have?
It is a 4 inch height fitting with a 3 inch NEMA loading depth. Take the 3 inch figure when you are sizing cable fill against your NEMA tray load class, not the 4 inch overall side rail height.
4) What part number do I quote for an 18 inch, 48 inch radius B-Line cable support fitting in aluminum?
B-Line part number 4A-18-CSF48. That single number covers the 18 inch width, 48 inch radius, 4 inch height aluminum fitting for Series 2 through 5 tray.
