I am looking for a heavy duty panic bar door lock to install outdoor on an offshore platform. The lock should be on one side mounted with panic bare and on the other with a lock. As the environment is offshore, I need something heavy duty that can resist the marine environment.

The Briton range of emergency exit equipment should be suitable for your requirements. The mechanisms have successfully been tested under the Building Corrosion Requirement test to Grade 3 (high corrosion). The lever access device is used in conjunction with the panic bars, pads and latches
