Why Squire’s heavy-duty Stronghold® range is supreme

Designed, engineered and made in Britain, the Stronghold® brand is Squire’s premium range of extra high security padlocks, padbars, chains, lock and chain sets and keysafes for commercial use.

Many highlights are the solid hardened steel lock body, electrophoretic anti-corrosion finish, hardened boron alloy steel shackle, anti-drill protection and high corrosion resistance for harsh environments.

Plus, the extra high security Stronghold® range has the added benefit of being tested and approved to the highest global standards by Sold Secure, CEN and LPCB, and supported by Secured by Design.
