B-Line Eaton series imperial cable tray and ladder, 4" Height, 27" Length, 6" Width, Series 2-5 vertical tee down, Aluminum, 24" Radius

A vertical tee down joins a straight cable tray run to a branch that drops away below it, so you get three legs meeting at one point with the branch heading down. The Eaton B-Line 4A-06-VT24 is the aluminum version for 6 inch wide, 4 inch deep tray, and it turns the drop on a 24 inch radius so cable bend radius is maintained through the transition rather than breaking over a sharp corner.

Allow for a fitting that measures 27 inches in length overall, with the drop swept on a 24 inch radius. That radius is the governing number when you are laying out around beams, ductwork or a wall face, so check the clear depth below the tray before you commit the hanger locations.

Aluminum. That is the usual pick for damp, coastal, wash-down and chemical exposure areas because it will not rust the way painted steel does once the coating is scratched during install. It is also the lighter option to hang, which matters on long overhead runs. Steel tray fittings are the alternative where you need higher load capacity or an existing run is already steel, and you should not mix the two in one run without a proper transition.

It carries CSA certification, so it can be specified on work governed by the Canadian Electrical Code. Have the submittal show the CSA mark against the 4A-06-VT24 part number if your inspector or spec section asks for certification evidence.

Yes, plan on them. The 4A-06-VT24 is the fitting body itself; splice plates, bolts and the hangers or trapeze supports at each leg are separate line items. Order splice hardware matched to the Series 2-5 aluminum rail so you are not mixing dissimilar metals at the joint.

Orientation of the branch. A vertical tee down, which is what the 4A-06-VT24 is, takes the branch below the plane of the main run. A vertical tee up sends it above. They are not interchangeable and cannot be flipped to swap function, so confirm from your riser drawing which direction the drop goes before ordering.

It weighs 15.9 lb, so it is a one-man lift, but it is a three-legged fitting on a 24 inch sweep and awkward to hold in position alone. Plan a hanger or temporary support at each leg before you set it, and account for that dead load plus the cable fill when you size your trapeze supports.
