The Squire Stronghold ST50S/2.5 is a high-security, marine-grade padlock designed to withstand the harshest environments. Manufactured in the UK, this robust padlock features a 50mm wide solid stainless steel body and a 10mm diameter stainless steel long shackle, offering exceptional resistance to corrosion and physical attack. It has been salt spray tested for 480 hours, making it ideal for marine, coastal, and extreme outdoor applications.

At its core is a highly secure, rekeyable 6-pin cylinder that provides over 250,000 key differs, alongside advanced protection against drilling, picking, and bumping. For added security, the padlock is key-retaining, meaning the key can only be withdrawn when the padlock is fully locked. Tested to CEN Grade 3, the ST50S/2.5 comes with a manufacturer's 10-year guarantee and is supplied with two keys.

Excellent service, and when it transpired that I had mis-measured one barrel, its replacement came very quickly. I can recommend Lock and Key
