An LPS 1175 SR4 door provides the very best protection against forced entry through an entrance. They are our most secure product and are yet to be breached successfully. The Product has been tested to resist an attack for an attack for a minimum of 10 minutes using a variety of tools including high powered cordless tools, felling axe, power drill, sledgehammer, disc grinder, jigsaw etc.

Each door will be thoroughly checked before dispatch by our quality control. This helps ensure quality and prevent standards falling below those of the LPCB or Secured by Design.

They are available as either fire exits or personnel's and can be fitted with glazing if required.
