Zip cuffs are flexible restraints made from durable plastic, designed for temporary immobilization of individuals. They are often used by law enforcement and security personnel due to their lightweight and easy-to-use nature. Unlike traditional handcuffs, zip cuffs can be quickly applied and adjusted to fit various wrist sizes. These restraints work similarly to cable ties, featuring a one-way locking mechanism that prevents loosening once secured. While they are effective for crowd control or during mass arrests, zip cuffs are intended for short-term use and should be replaced with more secure restraints when necessary.
