Extreme® 300 Series High Performance GrilleHigh Performance Security Grilles
Model Number: EPG324 and EPG324B
High Performance Rolling Security Gate
In high traffic areas that require access control, Cookson’s high performance security grilles provides a security solution that is engineered for longevity, opens 3 times faster than standard safety gates and comes with many advanced features.
Utilizing a variable-frequency direct drive, means there are not any sprockets or chains to wear or replace. This provides a security gate that reduces downtime with little to no maintenance while offering operating speeds of up to 24” per second. The smooth, high speed rolling gate is not only engineered for longevity, but easy to set up and install. Paired with our Apex SmartController, commissioning, setting limits and setting up status messages for the high performance roll up gate is simple. Even the plug and play wiring makes the grille’s operator installation a breeze while also accepting connections to virtually all activation systems. Available in either straight rectangular or offset brick patterns, multiple opening sizes, materials and finishes are available.
While the high performance gate features are great advantages, this safety gate also utilizes several advanced safety features. Built in UL-325-2010 (NEME) photo eye sensor beams and 6’ tall safegard light curtain, ensure that when anything passes through the grille opening, the rolling gate is immediately halted and the direction reversed.
High performance, maintenance free, high speeds, advanced safety features and easy operation and setup show why the Extreme 300 security gate is a high demand product for parking gate systems in parking garages, airports, malls, transportation hubs and any high traffic entrance with security grille needs.

Standard Materials and Finishes
The 300 Series Grille open air design provides increased visibility and ventilation. Curtains are assembled with heavy duty 5/16” diameter aluminum alloy rods spaced at 2” on the center with aluminum tube spacers specifically placed to create two pattern options:
- Brick Pattern
- Straight Pattern
Medium bronze anodized
Dark bronze anodized
Sensing Edge - Entrapment Protection Device
Designed with a flexible black rubber TPE material, our new sensing edge has two fins that conform to variations in the floor on both the interior and exterior of your door or grille ensuring a secure seal without requiring you to overset the bottom door limit. The sensing edge is easy to clean and remains free from rust and dirt stains, maintaining a fresh uniform appearance. With flexible 1" sealing fins, our sensing edges provide maximum protection while withstanding the elements.
Edges are tested and listed to UL 10B as a component of the rolling steel fire door assembly.
To determine the best entrapment device for your application, check out our Entrapment Device Protection Overview document.
Hood and Operator Covers
Metal cover to protect the coil or operator from exterior weather, debris or to meet OSHA or UL 325 safety requirements.Learn More
Powder Coating Grilles
Powder coat finish in more than 180 colors is available on perimeter components such as the aluminum bottom bar, hoods, wall angles, tubes and fascia. This finish is not available on the grille curtain.Learn More
Sloping Bottom Bar
CornellCookson's new low profile sloping bottom bar for the Extreme MicroCoil Grille and Extreme 300 Series High Performance Grille allows for a continuous uniform grille versus the traditional, bulkier pitch plates giving your opening a highly aesthetic, finished look.
Vibration IsolatorVibration Isolators effectively reduce the amount of vibration* caused by operation of doors and grilles.
*Vibration was reduced by14%+ on doors and grilles with vibration isolators installed compared to doors and grilles without the system
LED Visual Light KitThe LED Light Kit provides a high-visible status indication for overhead doors and grilles. Designed for challenging environments like fire and emergency services, parking garages, and warehouses, the effective LED light strips limit downtime, maintenance, and repair costs.
Seismic Performance Validation
We can provide project specific seismic calculations for all coiling doors that are mounted Face of Wall or Between Jambs to steel or masonry. Seismic performance validation is per ASCE 7-05.
Entrapment Protection Devices
Entrapment protection devices ensure that a motorized door or grille will not close on an object. If an object enters path of closure, the entrapment protection device will stop the door or grille from closing and return it to the fully open position.
Monitored Protection, Even at High SpeedsUL 325-2010 (NEMA 4X) compliant photo eye sensors allow for momentary contact operation – useful in parking garages and other high use openings. Interruption of the photo eye beam before the door fully closes causes the door to immediately halt downward travel and reverse direction to return to the fully open position.
SafetyGard Light Curtain TechnologyThe 6’ tall light curtain is installed within the guide and blends into the guide construction. If the grille is cycling and an object passes through the curtain beams the door will immediately halt downward travel and reverse direction to return to the open position.
