The Squire ST75S stainless steel container padlock is built for storage yards and container sites, delivering rugged, reliable security for shipping containers.

The ST75S uses a corrosion-resistant stainless steel body (80mm wide × 65mm high × 26mm deep) and a 12mm shackle, weighing around 830g, for outdoor use in harsh environments.

Security comes from a Squire Stronghold 6‑pin cylinder, with CEN Grade 3 certification, giving predictable, pick-resistant operation for day-to-day container lock boxes.

Each lock is supplied with 2 keys. It can be ordered in standard or restricted key sections, and offered in Keyed Differ (KD) on the shelf and Keyed Alike (KA) or Master Keyed (MK) configurations via the Keytrak Workshop, with typical 3–5 day lead times. Master keyed sets are also available to support future site expansion.

Ideal for shipping containers, storage containers, and container hire sites, the ST75S is designed to integrate with common container lock boxes and is ready for expansion as your site grows. Master keyed sets let multiple locks share one master key, simplifying management across a portfolio of containers.

For tradespeople evaluating options, the ST75S sits among the practical choices in heavy duty padlocks for containers and storage container locks, delivering durable stainless steel protection and flexible keying. For those seeking the best padlock for shipping container security, the ST75S offers reliable corrosion resistance, a proven 6‑pin cylinder and adaptable access control.
