5500.IP Intumescent Pack

Intumescent Pack to suit all 5600, 5500 & 5400 Series Cylinder Lockcases

When fitted to timber fire doors, the lockcase must be fitted in conjunction with an intumescent protection pack to ensure the integrity of the door is maintained in a fire situation. Because of the dimensional co-ordination of the Briton 5600, 5500 & 5400 Series lockcases, a universal intumescent pack is available which is suitable for all versions and all functions.

The Briton range of European profile cylinder mortice lockcases incorporates the Briton 5600 Series, Briton 5500 Series and Briton 5400 Series. Each lock series is built on the same dimensional platform which enables not only substitution of lock functions within each series but full interchangeability between lock series. All 3 lockcase series are available with rounded or square forends and strikes to suit the manufacturing and factory preparation of timber or metal doors. All 3 lockcase series are compatible with the Briton 75-29 cylinder range or any of the CISA cylinder ranges.
