DoorJammer - Secured by Design

DoorJammer products are award-winning and police accredited door security devices that can prevent unwanted entry to any room you are in and fast.

Being police accredited is a big deal to us. We have worked hard to design the very best products that also conform to the rigorous requirements of the Secured by Design product based accreditation award.

What is Secured by Design?

Secured by Design (SBD) is the official police security initiative. SBD’s product-based accreditation scheme – the Police Preferred Specification - provides a recognised standard for all security products that can deter and reduce crime.

SBD is the only way for companies like ours to obtain police recognition for security related products in the UK. There are many companies producing crime prevention products which have achieved Police Preferred Specification and we are proud to be one of them.

SBD membership requires products to not only be tested to relevant security standards but also be fully certified by an independent third-party certification body accredited by the United Kingdom Accreditation Service (UKAS).

Independent certification involves both the initial testing of our entire product range and regular re-testing as well as inspections of our production facility to ensure the correct processes are maintained constantly over time and ensuring that our products are high quality, secure and reliable.

Be sure of what you are buying

DoorJammer products are the original security device of their type and while there have been imitation products emerge on to the market following on from our success, DoorJammer is the only one that has achieved the police preferred specification SBD accreditation.

Don’t risk your personal protection device failing in the moment you need it most – be sure that you are purchasing a genuine DoorJammer product. DoorJammer and Lockdown are both painted in highly visible Classic Red and are never sold in any other colourway. Our patented design is built using the highest quality components - we only use high-grade steel to achieve DoorJammer's incredible strength. DoorJammer products will not loosen on their own and they will not break under pressure.

Don’t compromise on:

Secure Fit









The best way to ensure you are buying a genuine DoorJammer product is to avoid using shopping sites - official DoorJammer products can be purchased directly from our website.
