Gez: All the cabinets have the British standard kite mark, most have home office accreditation so you won't go wrong with many of them.
What ive found the cops when checking them, if they have foam inserts for holding guns will count the gun spaces, and only allow that amount of weapons on the certificate, where the cabinet will hold far more weapons, pull the foam bit out when it come to there inspection time,then there's no comment can be made ,to amounts of weapons held within reason .
