SQUIRE ST50CS Stainless Steel Stronghold Padlock Closed Shackle

The Squire Stronghold ST50CS is a premium, high-security closed shackle padlock designed to withstand the harshest outdoor and marine environments. Proudly manufactured in the UK, this padlock features a solid 50mm stainless steel body and a 10mm stainless steel shackle. Its closed shackle design significantly reduces exposure to physical attacks, making it highly resistant to cutting and cropping.

Equipped with a rekeyable 6-pin cylinder offering over 250,000 key differs, the ST50CS provides excellent protection against picking, bumping, and drilling. For added security, the lock is key-retaining, meaning the key can only be withdrawn when the padlock is fully locked.
