Post Office Fortress Design & Standards

Fortress Counters for Screened Format Post Office Branches were first introduced in 1967 to provide protection from a spate of ammonia attacks at the time. Thankfully these attacks have dwindled but the threats have remained.

Today Post Office Fortresses provide protection for post office staff and peace of mind for the general public. Designed to both withstand violent attack and provide ease of service, the security counter offers the perfect balance of protection and function.

Post Office Fortress Design Standards

Anti-Bandit Security Screen Design

Post Office Security GlassFrom July 2003, all sub post office security counter screens have to comply with the Anti-Bandit Screens Glazing Policy in Screened Format Post Office Branches, or Screen 2000. This dictates the minimum safety standards in the event of a deliberate and aggressive attack to gain entry to a fortress area.

KS Security screens are manufactured and installed to comply with the Post Office Ltd.’s standards of Screen 2000, as well as British Standard BS 5544.

Glazing Technical Specification

  • 11.5 mm, 5 ply Asymmetric Laminated Security Glass
  • Maximum Spall (protection from flying fragments of glass)
  • Secured with Dunlop High Modular Silicon DP2205
  • BS 5544 Compliant
  • Fully Welded Steel Frame with Speech Blocks
  • Frame Polyester Coated in Goosewing Grey to BS00A05

Attack Resistance

All post office anti-bandit screens must be capable of withstanding a manual attack of not less than 1 minute before a man size hole (315mm x 315mm) is made and manual attack of not less than 30 seconds before an arm size hold is made (112mm x 112mm). Under Post Office Ltd. test conditions the following tools were used:

  • Sledge Hammer
  • 60cm Long Jemmy
  • Club Hammer
  • Selection of Screwdrivers
  • Allen Keys
  • Spanners
  • Sockets and Wrenches
  • Mole Grip Pliers

All KS Security Post Office Fortress Screens are built to exceed this specification and have been rigorously tested and approved by Post Office Ltd.

Counter Design

A post office counter’s primary purpose is to provide a comfortable and functional place for staff to work and customers to interact, in accordance with Post Office IMREQ005 counter standards. However a Fortress Counter must also protect the staff from physical attack in conjunction with an anti-bandit security screen and other security measures.

Appearance & Attack Resistance

Our post office security counters are constructed in accordance with the Post Office Ltd. standards, which dictate the counter structure be capable of withstanding a manual attack of not less than 1 minute before a man size hole (315mm x 315mm) is made and manual attack of not less than 30 seconds before an arm size hold is made (112mm x 112mm). We achieve this by constructing a 6mm/3mm steel armoured counter that both meets the BS 5888 /G2 European standard EN1063 equivalent, which is finished in hard-wearing lino and attractive real wood.
