B-Line 4A-36-24-HX24 Eaton series imperial cable tray and ladder - Length 90 in, Width 36 in, Height 4 in - Aluminum

It's a Series 2-5 horizontal cross fitting for Eaton B-Line imperial ladder cable tray, used where four tray runs meet in the same horizontal plane. It joins 36 inch and 24 inch tray widths, so the main run through it is 36 inches wide and the branch legs are 24 inches. Side rail height is 4 inches, matching 4 inch deep ladder tray.

The fitting is built on a 24 inch radius. That is the figure to check against the minimum bend radius of the largest cable you are pulling through the intersection: if your cable calls for less than 24 inches, this cross works; if it needs more, you need a larger radius fitting. Radius also drives how much room the fitting takes up, which matters in tight ceiling spaces.

No. A horizontal cross like the 4A-36-24-HX24 keeps all four legs in the same plane, so it only handles a four-way intersection on a level run. If your branch drops or rises, you need vertical elbows or a vertical tee instead, set after the cross. Likewise, if only three runs meet, a horizontal tee is the correct fitting rather than a cross.

Plan for a 90 inch overall dimension on the run through the fitting, with 36 inch width and 4 inch side rail height. With a 24 inch radius on each leg, the intersection footprint is considerably larger than the tray width alone, so confirm your available ceiling or plenum space and support locations before you set the hangers.

Aluminum. That keeps the weight down for overhead work and gives it inherent corrosion resistance, which is why aluminum tray is common in wastewater, chemical, coastal and other damp or corrosive environments where plain steel would need galvanizing or paint. Aluminum tray also carries less load than an equivalent steel section, so check your cable fill weight against your span and support spacing.

58 pounds bare. That is the dead load before any cable, so size your trapeze hangers and rod anchors at the intersection for the fitting plus cable fill. At 58 pounds and 90 inches across, it is a two-person lift into position.

Order Eaton B-Line part 4A-36-24-HX24. The number breaks down as 4 inch rail height, aluminum, 36 inch main width, 24 inch branch width, horizontal cross with a 24 inch radius. It carries CE certification.

The 4A-36-24-HX24 is supplied as the cross fitting itself. Splice plates, connector hardware and the hangers or trapeze supports at the intersection are separate items, so add them to the order along with any tray covers if the run is covered. Match the splice plates to 4 inch aluminum ladder tray in the same series.
