3.1.5 Bolt— Bolt seals consist of a metal rod, threaded or unthreaded, flexible or

rigid, with a formed head, secured with a separate locking mechanism.

3.1.6 Cinch or Pull-Up— Cinch or pull-up seals are indicative seals. They consist

of a thin strip of material, serrated or non-serrated, with a locking mechanism attached

to one end. The free end is pulled through a hole in the locking mechanism and drawn

up to the necessary tightness. Cinch or pull-up type seals may have multiple lock

positions. These seals are generally made of synthetics such as nylon or plastic. They

should not be compared to simple electrical ties.

3.1.7 Twist— Twist seals are made of steel rod or heavy gage wire of various diameters, which is inserted through the locking fixture and twisted around itself by use of a tool.

3.1.8 Scored— Scored seals consist of a metal strip which is scored perpendicular

to the length of the strip. The strip is passed through the locking fixture and bent at the

score mark. Removal of the seal requires bending at the score mark which results in

breakage of the seal.

3.1.9 Label— Label seals are frangible seals consisting of a paper or plastic

backing with adhesive. The combination of backing and adhesive are chosen to cause

the seal to tear when removal is attempted.

3.1.10 Barrier Seals – A barrier seal is a seal designed to provide a significant barrier

to container entry. A barrier seal may, for example, enclose a portion of the inner

locking rods on a container. Barrier seals may be designed to be re-usable.
