B-Line Eaton series imperial cable tray and ladder, 4" Height, 42.0625" Length, 6" Width, Series 2-5 horizontal bend, Aluminum, 90° Angle, 36" Radius

It is a 36 inch radius 90 degree bend measuring 42-1/16 inches overall. Allow room for the full 36 inch sweep off the centerline plus the tangent ends, so a tight corner or a wall within about four feet of the turn point will not take this fitting. If space is tight, a shorter radius bend is the fitting to look for.

Large-radius fittings exist because of cable bend radius limits. A 36 inch sweep suits heavy power or large-diameter fiber and control cable that cannot be pulled around a tight corner without damage. If you are running small conductors only, a smaller radius bend takes up far less ceiling space. This fitting turns the run 90 degrees in the horizontal plane, not up or down, for elevation changes you need a vertical inside or outside bend.

Aluminum. That makes it a reasonable pick for damp, coastal, or corrosive areas where plain steel would need coating, and it keeps the fitting light at 13.235 lb so one person can set it on the supports. Keep the tray system all one material where you can, mixing aluminum tray with dissimilar metal hardware invites galvanic corrosion.

The 4A-06-90HB36 is sold as the bend fitting itself. Splice plates and their hardware are ordered separately, and you need a set at each end where the bend meets a straight section. Plan supports near the fitting as well, most installs hang the bend rather than cantilever it off the adjoining straights.

CE marked. That is the marking listed for the 4A-06-90HB36 Series 2-5 aluminum bend. If your specification calls for a specific NEMA tray class or a load rating, confirm that against the series data for the straight sections you are pairing it with.

Order Eaton B-Line part 4A-06-90HB36. The number reads out as the spec: 4 inch aluminum rail, 06 for 6 inch width, 90 degree horizontal bend, 36 inch radius. Distributors cross-referencing it will find the same fitting under that MPN.
