B-LINE 4A-09-90VI48 – Frequently Asked Questions
1) What does the B-Line 4A-09-90VI48 vertical inside bend actually do in a cable tray run?
It turns a cable tray run 90 degrees in the vertical plane, bending inward (toward the cable side of the run) rather than outward. It is a Series 2-5 vertical inside bend in aluminum, 9 inches wide and 4 inches deep in the tray profile. If your run needs to rise or drop and the bend curves away from the cables instead, you need a vertical outside bend, not this fitting.
2) How much space do I need to allow for a 48 inch radius vertical bend in a cable tray run?
Allow for a fitting that measures 55.188 inches along its length, 9 inches wide, 4 inches high, on a 48 inch radius at 90 degrees. Lay that out on the elevation before you set your hangers, because a 48 inch radius bend eats a lot more vertical and horizontal space than a short radius fitting and it is the usual reason a run has to be re-coordinated against duct or structure.
3) Is the B-Line 4A-09-90VI48 tray bend CSA certified?
CSA is the certification carried on this Series 2-5 aluminum vertical inside bend. That is what most Canadian jurisdictions and a lot of institutional specs ask for on tray fittings.
4) Does the B-Line 4A-09-90VI48 come with splice plates and hardware?
Order splice plates and connection hardware separately. The 4A-09-90VI48 is the vertical inside bend itself, and each end that lands on a straight tray section needs its own splice connection, so count two sets per fitting when you build the material list.
5) How heavy is this aluminum cable tray bend for handling and hanger sizing?
15.9 lb for the fitting itself. Light enough for one person to set on a lift, but at 55.188 inches long you will normally want a hanger on each side of the bend rather than trying to cantilever it off the adjoining straight section, and the cable fill weight is what actually drives your support design.
6) Why choose aluminum cable tray fittings over steel?
Aluminum is what this bend is made from, and it is the usual pick where weight matters on long overhead runs or where corrosion is a concern, since it does not rely on a coating the way galvanized steel does. Steel is chosen where higher load capacity per span is needed. Whichever you use, keep the whole run in one material: mixing aluminum fittings into a steel system creates dissimilar metal contact at every splice.
