HOME > Pull tight seals - Smooth flat strap > DuoLoop


The DuoLoop is a variable length seal with a unique dual-jaw mechanism. The security seal incorporates stainless steel jaws for a smooth, user-friendly fastening action.

The dual locking mechanism allows for a variety of options, including being able to use the second loop as a label capture, or looping it through just to keep the strap from protruding. In any case, as long as both jaws are used, the double locks provide a bigger hindrance for tampering.
