    Default Chatwood mattresses

    Does anyone have any diagrams, specifications etc. for the mattresses Chatwood used to use in their strongroom doors please?

    Chubb's modern spec is online as a PDF if it's of any interest, think it's only on the African distributor Bishopsgate site though, no longer on Gunnebo or the others.

    interesting that the Chubb archives says Chatwood's spiral reinforcement (linked as said mattresses) was considered far superior to Chubb's twisted Tangbar spiral. Until I read that I had always assumed the big manufacturers had all been using combinations of both types in their vault installations.
    Also interesting that the UK Post Office was still using it for strongrooms built in the 1990s...
