DuraGrille™ Rolling Security Grille


Rolling Grille Doors

When security and visibility are primary considerations, choose Raynor’s attractive rolling DuraGrille security grille. The grille pattern, available in straight or brick, offers an unobstructed view of displays and merchandise. DuraGrille security grilles offer protection against theft and vandalism, all with a contemporary look. DuraGrille security grills are ideal for storefronts and interior applications, such as concessions, cafeterias, and retail shops.

DuraGrille Features and Options

Raynor DuraGrille rolling grille doors are available with numerous features and options, including those listed below.


Offered in a contemporary brick pattern or traditional straight pattern (left), grilles are constructed of 5/16” mill-finished aluminum rods with 9″ center-to-center interlocking links.

Aluminum Guides

Extruded aluminum guides are lined with a replaceable wool pile strip to reduce wear and provide quiet operation.

Counterbalance System

A torsion-spring-operated system, enclosed in a structural steel barrel, effectively counterbalances the security grille for a minimum of 15,000 cycles. Higher cycle torsion springs are also available.

Bottom Bar

An extruded aluminum bottom bar reinforces the curtain and provides smooth operation.


Manually-operated grilles are provided with slidebolt locks. Other locking options are available.

Increased Security

6” center-to-center link spacing provides added protection.

Curtain Hood

Optional curtain hood has rolled edges and is formed from 24-gauge, hotdipped galvanized steel, or aluminum.

Head Plate Cover

Head plate covers are offered for an attractive, finished appearance and help to protect your investment by keeping out dust and grime.

Auto Lock

Auto lock prevents the curtain from being forced open.

Motor Cover

Motor covers are helpful for noise reduction and provide an attractive look.
