Artist Jenni Robson painted a sunny scene on Leicester-based JCK’s Styro doorset before security testing to PAS 24.

“The artwork was engraved onto the face of the door and painted in watercolours and then sealed,” said Anthony Kellett, JCK director.

“The door caused quite a stir at Chiltern Dynamics and it did pass the tests with flying colours, despite it being Friday 13th.”

JCK already has BM TRADA Q-Mark certification under the police Secured by Design initiative.
