A zip tie, also known as a cable tie, is a type of fastener used to hold items together. It is made of plastic, and it has a flexible strap with a ratchet mechanism. To open a zip tie, you insert the end of the strap into the ratchet and pull on the strap. The ratchet will engage, and the strap will tighten around the object you are trying to secure. To release the zip tie, you squeeze the lever on the ratchet and pull on the strap. The ratchet will disengage, and the strap will loosen.
Zip ties are versatile and inexpensive, which makes them a popular choice for a variety of applications. They are often used to secure cables, wires, and other objects. They can also be used to create temporary repairs or to hold items in place while you work on them. Zip ties are available in a variety of sizes and strengths, so you can choose the right one for your needs.
