Barrier seals provide the maximum protection for shipping cargo via trucks and containers.
Barrier seals are installed on the keeper bars of the shipping container doors to secure both doors.
They are easy to install and require no special tools.
The barrier seal resists physical attack from saws, cutting sheers, bolt cutters, levering by crowbar, impact by hammer, etc.
These seals can only be removed using a cutting wheel, which normally takes about 20 minutes.
Barrier seals are a one-time use product.
For added security, all of our barrier seals have matching serial numbers on key components.

- LOCKING BAR
The 2-piece locking bar (.25 inch thick steel) fits keeper bar spacing ranging from 7.25 inches to 14.375 inches center-to-center.
- LOCKING PIN
A locking pin (.5 inch diameter) with locking mechanism (serial numbered) permanently couples the 2-piece locking bar assembly.
