Thomas & Betts YLS-7.9-200BC CBL TIE 100LB 8IN 316SS BLACK COAT

Yes. The band is 316 stainless steel, which is the marine and chemical grade of stainless, and it carries a black coating over the steel that adds a second barrier and cuts glare. That combination is what people specify for rooftop, coastal, tunnel, wastewater, and food plant wash-down work where nylon ties break down under UV or chemicals.

Rated tensile strength is 100 lb (440 N) on a band 0.311 in (7.9 mm) wide and 0.014 in (0.36 mm) thick. That is the loop's pull rating, not a hanger rating: use it to bundle and restrain cable, hose, tags, or signage against a support, and use rated clamps or straps where the tie would be carrying dead weight on its own.

Ball-lock stainless bands are pulled tight through the head and then cut off flush, so you want a stainless tie tension-and-cut tool. They can be started by hand, but hand-tightening alone will not reach the band's rated tension and leaves a sharp tail. Budget for the tool if you are installing any quantity.

Two reasons buyers pick the coated version: the coating is a dielectric-style barrier between the steel band and what it is strapped to, which helps where you do not want bare stainless bearing directly on a dissimilar metal or a jacketed cable, and black hides the hardware on architectural, signage, and exposed ceiling work. Mechanically it is the same 316 stainless band underneath.

Selling unit of measure is each, so you can order the exact count you need rather than a full carton. The part number to specify is YLS-7.9-200BC.

A 316 stainless band is the usual answer where nylon is ruled out by heat or smoke requirements, because the band is steel rather than plastic. Confirm the specific temperature and plenum requirement on your drawing against the coating, since the black coating is the temperature-limiting element, not the stainless.
