B-Line Eaton series Flex tray wire basket tray, Reended for exterior and corrosive applications, Hot-dip galvanized, Steel, 15.8" actual area inside t

Yes. The FT4X4X10 HD is hot-dip galvanized steel and is recommended for exterior and corrosive applications, which is why it suits rooftop runs, wash-down areas, water treatment plants and unheated industrial spaces. Hot-dip galvanizing after fabrication coats the cut wire ends as well, unlike pre-galvanized tray, so it holds up better where moisture and chemicals are present. It also carries a CSA certification.

The FT4X4X10 HD gives 15.8 square inches of usable area inside the tray. That is the number to use against your cable fill calculation, not the nominal 4 by 4 dimensions, because the wire mesh sides curve and the bend radius of the cable eats into the corners. For a small riser bundle of data or control cable it is generally plenty; for large power feeders in a main run, step up to a wider tray width.

Same 4 inch deep flex tray profile, different finish. The HD suffix on FT4X4X10 HD means hot-dip galvanized, which is the finish called out for exterior and corrosive duty. Pre-galvanized steel basket tray is for dry interior locations only. If your drawing says exterior, wet, or corrosive, the HD is the part that matches; ordering the standard finish to save a little will cost you the run.

Wire basket tray like the 4 inch deep FT4X4X10 HD is the choice for low-voltage, data and control cable where you want open airflow, easy mid-span drops and field cutting with bolt cutters. You form bends, tees and risers on site instead of ordering fittings. Ladder or solid-bottom tray makes more sense for heavy power feeders, for runs needing a defined bottom support at close intervals, or where a solid barrier or cover is specified.

Yes. What ships here is the tray section itself, model FT4X4X10 HD, one 118.312 inch stick. Splice hardware, wall brackets, trapeze or center-hung supports, ground straps and any hold-down clamps are separate line items. Plan on matching hot-dip galvanized hardware so you do not put plain or electro-zinc fasteners into an exterior or corrosive run and create the weak point in the system.

The FT4X4X10 HD carries CSA certification, which is what a Canadian inspector looks for on cable tray. Note that basket tray still has to be bonded as a continuous grounding path per code, so budget for bonding jumpers across each splice.
