B-Line Eaton series imperial cable tray and ladder, 6" Height, 30" Length, 30" Width, Series 2-5 horizontal cross, Aluminum, 12" Radius

The 6A-30-HX12 is built for 30 inch wide cable tray with a 6 inch side rail height. Both the length/depth and the width are 30 inches, which is what you would expect on a cross where all four legs land on 30 inch tray. If your run is a different width, you need the matching width fitting instead, since cross fittings are not field-adjustable for rail spacing.

This is a Series 2 through 5 fitting, so it is intended to mate with B-Line tray in those series at 6 inch rail height and 30 inch width. Rail profiles and splice hole patterns differ between tray families, so match the series on the fitting to the series on your straight sections rather than mixing.

Use a cross where four tray runs meet at one intersection, all in the same plane. A tee only handles three legs. The 6A-30-HX12 is a four-way horizontal fitting, so it is what you order where a main run continues straight through and branches go off both sides at the same point. If only one branch leaves the main run, a tee is the correct part and the cross would leave you an open fourth opening to plate over.

Order B-Line part number 6A-30-HX12. Reading the code: 6 is the rail height in inches, A is aluminum, 30 is the tray width, HX is horizontal cross and 12 is the bend radius. Distributors cross-referencing it will also find it under UPC 781011210496.

Yes. The 6A-30-HX12 cross is the fitting body only. Each of the four legs connects to adjoining straight tray with splice plates and hardware, so budget four sets per cross and match them to your tray series. Supports at or near the intersection are also separate.
