The Multiguard is a high security steel expanding trellis grille system. The security door is fully framed, suspended from a top track on rollers and has a bottom guide track, which provides high resistance to violent attack. The retractable grille is easy to operate and requires minimum to no maintenance. The attractive lattice designs allows the grille to stack to 20% of its opening size. The removable bottom track makes concertina door ideal for entrance door security where unrestricted access is required. We keep multiguard in stock for a short installation lead time. Available in either white or black powder coated finish. Multiguard can protect unlimited shop front width and has a maximum height of 3 metres. Multiguard is recommended by New Zealand insurance companies.
