HOME > Pull tight seals - Smooth flat strap > TeraLock


TeraLock is a user-friendly variable length security seal designed with high breaking strengths in mind. A stainless steel locking jaw provides a smooth locking action and is fixed in place with a heat welded cap to enhance security.

TeraLock Type-X is the new and improved version with a tail-keeper slot above the locking chamber to provide a simple way to keep excess protruding tail from being a hindrance or safety hazard. Ruler scale along the length of the tail allows pull to tighten guide, and allows easy detection of any tampering attempt.
