Insurance Approval - Diamond Security Levels - Stronghold's philosophy is to continually work with all of the major insurance companies and accreditation houses both in the UK and Europe. We test all new products in-house to ensure that we conform to all the relevant security standards as recommended within governmental guidelines. To enable us to enhance the worthiness of our products we have set out our own accreditation to run along side and improve on what is generally available to designers and manufacturers. The Diamond Security Level - Stronghold believe, will give the consumer added value – In Quality, Security, Practicality and Value for Money.

Diamond 5 – High Security Level This level gives high physical security to combat the determined thief. Products are produced with a commercial grade of locking systems, steels and protective finishes. Test procedures are in line with the sold secure silver accreditation but with Strongholds equivalent toolkit. All criteria in manufacture is based on expert design and manufacture. Heavier than the diamond 7 because of commercial restraints but highly effective in the discharge of its performance.
