Closed Shackle Padlocks

Yes, significantly. Independent and magazine tests consistently show that closed shackle padlocks are far harder to remove than open shackle types. Because the shackle is shielded by the body, it’s extremely difficult to reach with bolt cutters or saws.

In one test, a small ABUS Discus padlock outperformed several larger high-security models because the testers simply couldn’t reach the shackle with cutting tools. This design principle is why discus and shutter padlocks are classed as closed shackle by most insurers.

Most high-quality security chains have an elongated end link that allows one link to pass through another.
You only need to secure a single link into the padlock shackle, meaning even a tight closed shackle design can accommodate the chain easily. If your chain doesn’t have a long end link, we can recommend compatible models that do.

Many insurance providers specify a closed shackle padlock as part of their security requirements. If you want to be completely certain, confirm with your insurer what they define as “closed shackle.” In most cases, discus, block, and shutter padlocks qualify under this definition.

If needed, Padlocks.co.uk can liaise directly with your insurance company to confirm compliance and provide documentation to support your installation.
