  • Grilles remain fully functional after the blast and can be used as an emergency exit
  • Grilles prevent looting after glass has been blown out

Vulcan LogoExtendor Vulcan is a certified retractable security grille, with LPCB accreditation to LPS 1175 SR2.

Providing a high level of security for windows and doors, the Extendor Vulcan retractable grille is certified by the LPCB to LPS 1175 SR2, and is Secured by Design approved. As such, these grilles are insurance approved. Vulcan has also been successfully bomb blast tested in conjunction with glass backed anti-shatter security film.

The Vulcan and Eclipse grilles are the only security grilles certified to protect against bolt cutters. For buildings requiring high security, Vulcan grilles are sometimes used on the upper floors, and Eclipse on the ground floor, since both grilles are visually the same.
