Thomas & Betts YLS-7.9-360BC CBL TIE 100LB 14IN 316SS BLACK COAT

316 stainless is what you use where nylon gives up. The YLS-7.9-360BC is made from 316 stainless steel, the marine grade with molybdenum added for chloride resistance, so it holds up in salt air, wash-down food plants, wastewater, and chemical exposure. Nylon ties degrade under UV and heat and creep under sustained load. If the run is indoors, dry, and conditioned, nylon is cheaper and easier to install; outdoors, on a rooftop, near the coast, or anywhere it gets hosed down, stainless is the correct call.

Yes. A ball-lock stainless tie like the YLS-7.9-360BC is not a hand-pull item the way a nylon tie is. The strap feeds through the head, a hardened ball wedges against it, and you need a stainless tie tensioning tool to pull it to the correct tension and shear the tail off flush. Doing it by hand with pliers leaves a sharp tail and an under-tensioned bundle. Budget for the tool on the first job; it is reusable across every stainless tie size.

The coating on the YLS-7.9-360BC is a black polyester jacket over the 316 stainless strap. Two reasons people specify it: it keeps the bright metal from flashing on architectural or exposed runs, and it puts a dielectric layer between the strap and whatever it is bundling, which matters when you are tying to painted steel, aluminum, or dissimilar metal and want to avoid galvanic contact and abrasion of cable jackets. The 100 lb (440 N) tensile rating is the strap rating; the coating is protective, not structural.

The YLS-7.9-360BC is rated 100 lb (440 N) tensile. That is a loop-tension rating for a 0.311 inch wide, 0.014 inch thick strap, which puts it in the light-to-medium duty range for stainless ties: signage, cable bundling on tray and ladder, hose and conduit attachment, tagging on poles. It is not a structural support member. If you are hanging heavy feeder or need a banding-grade hold, step up to a wider, thicker strap rather than doubling these.

Order it as Thomas & Betts YLS-7.9-360BC. The designation reads directly off the tie: YLS is the coated stainless ball-lock series, 7.9 is the strap width in millimeters, and 360 is the strap length in millimeters, with BC for black coated. That is the number to put on a submittal or a counter order.

The YLS-7.9-360BC is catalogued each, so the order quantity you enter is the number of individual ties. On a large pull that is worth checking against your count, since stainless ties are commonly handled in bulk on the job.

Less than a bare stainless tie will. The YLS-7.9-360BC carries a black coating over the 316 stainless strap, which softens the edge contact against jackets, painted steel, and aluminum. The strap is only 0.014 inch thick and 0.311 inch wide, so on soft or thin-walled jacketing you still tension to snug rather than maximum, and let the coating do the bearing work.
