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.

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.
