Thomas & Betts L-11-50-9-C Standard, 100 Pack

Temperature rating on the L-11-50-9-C is -40F to 185F, which covers attic, crawlspace and most rooftop conduit runs. It is molded from Nylon 6.6 in natural color. Natural nylon is not UV stabilized, so for long-term direct sun exposure use a black UV rated tie instead.

The L-11-50-9-C is a single size of nylon 6.6 cable tie in natural, 11 inch nominal length and 0.187 inch width, handling bundles up to 3 inches in diameter and sold in packs of 100 of that one size. The Burndy CTASST is a Unirap canister variety pack supplying an assortment of tie sizes in both natural and black. Pick the L-11-50-9-C when you are repeating one bundle size across a job and want a consistent 11 inch tie on hand; pick the assortment when you want mixed lengths and both colors in one container.

Not interchangeably. The Thomas & Betts L-11-50-9-C carries military standard part number MS3367-7-9, so it is the item to order when a drawing or spec calls out that number. The Burndy CTASST is a Unirap canister variety pack of assorted ties and is identified by its series rather than by a military standard part number, so it serves general bundling work rather than a MS3367 callout.

It carries a UL 94 V-2 flammability rating. That is the rating inspectors and spec writers look for on general nylon ties in panels and raceway support. No other listing or rating is claimed for this tie.

Yes. It is cross-referenced to MS3367-7-9, so it can be supplied against government and defense bills of material calling for that part number. Useful if you are procuring to a drawing rather than a commercial catalog number.

The L-11-50-9-C ships 100 ties per bag, and orders go in multiples of 100. The full case quantity is 5000. Weight runs about 5 lbs per 1000 ties, which matters if you are staging material by the case for a large pull.

Approved application tools for the L-11-50-9-C are the ERG50, QC-100, L-200 and L-400-C. Any of those will tension to a repeatable setting and shear the tail flush, which is what you want in a panel where a protruding tail can chafe a conductor. The ties can be pulled by hand, but hand tensioning gives you no consistency across a bundle and leaves a sharp tail.

The Thomas & Betts L-11-50-9-C carries a temperature rating of -40 F to 185 F and a UL 94 V-2 flammability rating, and it is a natural nylon 6.6 tie. Natural nylon is not a UV-stabilized color, so for sustained direct sunlight a black tie is the usual call -- the Burndy CTASST Unirap canister includes black ties as well as natural, which is one reason buyers keep an assortment on the truck. For unheated interior spaces and cold-weather equipment rooms, the L-11-50-9-C temperature range covers the condition directly.

The Thomas & Betts L-11-50-9-C is rated for use with the ERG50, QC-100, L-200 and L-400-C application tools, so it fits a workflow where ties are tensioned and cut off to a consistent tension. The Burndy CTASST is a Unirap canister assortment intended for hand installation of mixed tie sizes. If your crew standardizes on a tensioning tool, the L-11-50-9-C is the tie to match to it.
