Knightguard® Rollergrilles are custom made in a choice of 2 designs: Econolink or Ultra Security Grilles.

The Econolink is a very popular rollergrille offering a physical security barrier on doors and windows, with airflow and visibility, for an economical cost. Econolink grilles are constructed from heavy duty 12.7mm extruded aluminium tube and strong injection moulded fibreglass reinforced links, for superior strength.

• Links set in a brickwork pattern at 200mm intervals
• Heavy duty aluminium tubes finished in anodised satin silver 
• Tubes spaced at 45mm (centre to centre)
• 3 tubes per link (for added strength)

Knightguard's Ultra Security is a tough, but attractive option when a heavy duty Rollergrille is required. Constructed from heavy duty 19mm extruded aluminium tube and high tensile aluminium links, Ultra Security offers a premium security barrier. The standard finish is anodised satin silver, but custom powder coat finishes are available on request.

• Connected by high tensile 30mm wide, T594 extruded aluminium links
• Links set in a brickwork pattern at 500mm intervals
• Tubes spaced at 70mm (centre to centre)
• 2 tubes per link (for additional strength)
• Finished in anodised satin silver or custom powder coat colour

Both available as a manual spring balanced operation or motorised with high quality tubular motors (dependent on size).
