Self locking zip tie fasteners designed for single use sealing and portable locking. These ties lock by pulling tight and require no tools to install. Once locked the seal cannot be reopened, and removal destroys the tie so it cannot be reused. Key benefits Quick and tool installation: pull tight to engage the self locking mechanism for fast, consistent sealing. Tamper evident single use seal: once locked the tie cannot be reopened without cutting or breaking, providing clear evidence of tampering. Portable and easy to carry: lightweight and simple to apply by hand for on the spot sealing and tagging. Flexible removal options: remove by steel cutter for fast, clean removal or break by hand when designed to allow hand breaking. Main features Self locking design that secures with a single pull to lock. Single use only sealing that prevents reuse after removal. No tools required to lock; removal requires cutting or breaking. Suitable for signage locking and a wide range of security and sealing tasks.
