Our 11-inch Nylon Cable Ties are available in either removable or permanently locking versions and will not scratch or damage evidence. Releasable ties will allow a crime lab to remove weapons from the Weapons Collection and Storage Boxes in which evidence has been secured, then re-secure the weapons back into the box using the same cable ties. Permanently Locking Ties feature a pull-tight locking closure and will not release, making them ideal for securing evidence tags to evidence.
