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 4X) 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.

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.
Guide-Mounted InterlocksAn electrical cutout switch to prevent motor operation if locking device is not first disengaged.
A wide variety of locking options are available to meet your security needs.
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.
