Extreme® 300 Series High Performance Grille

High Performance Security Grilles

High Performance Rolling Grille

For building owners and maintenance managers tired of repairing or replacing commercial doors or security grilles, the Extreme® 300 Series High-Performance Grille is the answer. Ideal for parking garages, airports and transportation hubs or other high traffic openings, the 300 Series High-Performance Rolling Grille operates up to 3 times faster than standard overhead coiling grilles and is engineered for 300,000 open and close cycles. If you need a high-speed grille, the 300 high-performance grille has fast opening speeds of up to 24" per second and closes at 12" per second. This maximizes productivity, smooths traffic flow and reduces downtime in high traffic applications.

To ensure maximum uptime, the 300 Series Grille requires practically no maintenance other than routine checks and no replacement parts. The commercial grille’s compact operator features a variable-frequency drive that ensures a smooth start and stop – reducing wear and tear on both the overhead grille and the operator. In addition, the operator’s direct drive design means there’s no sprocket and chain to wear or replace. It accepts virtually all security activation systems and features a 2-year operator warranty and a 2 year/300,000 cycle component warranty.

Our Apex SmartController intelligent control panel featuring plug and play wiring makes installing and servicing the 300 Series Security Grille easier than ever before. The LCD screen communicates safety grille status messages, provides easy-to-follow instructions for roll up grille commissioning, and electronically sets door limits. When the security grille limits are set, they are continuously monitored and adjusted.

When you need fast speeds, maintenance free solutions and easy to install and use security that still provides visibility and air flow, the 300 Series High Performance Grille is the only security answer you need.

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.

Performance Upgrades
Seismic Performance Validation
We can provide project specific seismic calculations for all coiling doors that are mounted Face of Wall to steel or masonry. Seismic performance validation is per ASCE 7-05.

Safety and Protection
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 Interlocks
An 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 Speeds l
UL 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 Technology
The 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.
