Zip Ties 12 inch (100 Pack), Black, 50lbs Tensile Strength, UV Resistant Cable Ties for indoor and outdoor use, by Karoka

These 12-inch black zip ties are absolutely fantastic. The 100-pack is a great value, and the 50 lb tensile strength is no joke—they're incredibly strong and reliable. I've used them for everything from tidying up cables indoors to securing items in the yard, and they've held up perfectly. The UV-resistant feature is a huge plus, giving me confidence that they won't become brittle or break down after being exposed to the sun. The self-locking mechanism is secure and easy to use, and I haven't had a single one fail. If you need dependable cable ties for any indoor or outdoor task, these are the ones to get. Highly recommend!

Very well made ties. Not cheap and thin like others. Very hard to break by hand and long enough that you could use them for anything

Good sturdy material. Good length. Good ridges for Good locking.

These 12-inch UV-resistant zip ties are strong, reliable, and perfect for both indoor and outdoor use. With a 50 lb tensile strength and a bulk pack of 4,000, they’re an excellent value for anyone needing durable ties for HVAC, electrical, or general projects. The price is far better than what most HVAC companies charge, making this a smart and economical choice.

Not the same quality as the smaller pack.. visible differences, like different type of plastic, higher distance between the teeth.. and tested the strength of a few ties between these ones and the original ones, and they seem to break a bit easier..
