ABB Catamount L-7-50-0-C Cable Ties, UV Black (100 Pack)
Distributor grade UV black ties that suit outdoor runs, at a higher cost per tie than bulk packs.
The short version
- People running coax, network or low voltage cable outdoors
- Garage, garden and fence jobs that sit in the sun
- Anyone tired of cheap ties snapping while being tightened
- You need reusable ties; buy releasable or hook and loop ties
- You need more than 50 lb of holding strength
- The ties are only for indoor cord tidying, where a cheaper natural tie works
What owners like
- Thomas & Betts ties are a common answer when tradespeople and hobbyists are asked which ties hold up outdoors

- Fewer ties snapping during install than cheap hardware store packs
Common complaints
- Costs more per tie than bulk no name packs
- Cannot be released, so a misplaced tie has to be cut off
- Spec details such as the temperature ceiling differ between distributor pages

Questions
Are Thomas & Betts L-7-50-0-C ties UV resistant?
Yes. They are black nylon 6/6 that distributors and ABB's part description list as UV and weather resistant for indoor and outdoor use.
Is the L-7-50-0-C the same as Catamount?
Yes. Thomas & Betts is owned by ABB, and the same part number is now sold under the Catamount brand.
How big a bundle will a 7 inch 50 lb tie hold?

Why use black cable ties outside?
Black UV stabilized nylon resists sunlight breakdown. Forum users report uncolored and cheap colored ties going brittle much sooner outdoors.
