Basic Selection Checklist

Determining whether a side-folding or upward-coiling security grille is best for your project can be a matter of the application, opening conditions, or personal preference. Some basic design considerations are listed below. If you need additional assistance in making a selection to meet your needs, please contact us.

SIDE-FOLDING SECURITY GRILLES
A side-folding security grille is often used in applications where:

• Headroom is limited
• There is limited or no clearance above the opening or on one side of the opening
• The grille must follow a radius
• The opening is extremely wide
• Electric operation or electrically-controlled emergency egress is not necessary.

UPWARD-COILING SECURITY GRILLES
An upward-coiling security grille is ideally used in applications where:

• Electric operation is necessary
• Electrically-controlled emergency egress is desired
• The grille is subjected to heavy usage (an optional high usage package is available)
• In applications with no clearance on one or both sides of the opening.
