Transport Security, Inc. Adds Security Seals, Giving Fleets a Single Source for Locks and Seals

Written By: Transport Security, Inc.

WACONIA, Minn., March 25, 2026 — Transport Security, Inc. (TSI) today announced a full range of cargo security seals — bolt, cable, plastic, and metal strap — now available alongside its ENFORCER® lock line. Fleet operators that already buy ENFORCER® locks can now consolidate seals through the same vendor, reducing supplier count, simplifying procurement, and receiving one invoice for all physical security products.

The new seal line carries C-TPAT, ISO 17712, and ISO 9001 certifications, making it suitable for regulated supply chains, cross-border freight, and compliance-sensitive operations. All products are warehoused at TSI’s facility in Waconia, Minnesota, enabling fast domestic fulfillment in bag or case quantities.

TSI has been fulfilling seal orders on request for several years. The company is now formally expanding the offering to its full lock customer base, so fleets no longer need a separate seal vendor. Customers who consolidate seal purchasing through TSI benefit from competitive fleet pricing. Prime Inc. is the first major trucking fleet to move its seal purchasing to TSI under the expanded program.

“A fleet security director managing 500 trailers might buy locks from us, seals from a second vendor, and custom-numbered seals from a third,” said John Magee, VP of Sales at Transport Security, Inc. “Now that’s one vendor, one call, one invoice. They already trust ENFORCER locks on their trailers — adding certified seals from the same source is the obvious next step.”
