High Performance Compact Security Grilles
When you need security in an opening with limited vertical space, our Extreme 300 Series MicroCoil Grille is the answer. Perfectly engineered to occupy the smallest amount of headroom on the market, our high performance compact grille not only coils in nearly 50% less room then other security grilles, but also gives you high performance. The MicroCoil Grille is engineered to handle at least 300,000 cycles (opens/closes) at speeds of up to 24” per second. But, with the MicroCoil Grille, higher speeds do not mean you get a loud and clunky security grille. Our low headroom parking security grille’s patented nested link system actually minimizes noise and vibrations - making it one of the quietest and smoothest coiling parking garage gates available today.
In addition, ADA compliance is made easy. With most parking garage openings averaging 9’6”, accommodating parking spaces for 8’2” handicap accessible vans as required by ADA has become a huge challenge. Taking up less than 14” coiled grille headroom space at it’s largest (and often even smaller), the MicroCoil security grille allows almost any parking facility the opportunity to install rolling security grilles and still be in compliance.
Our compact parking lot security gates are easy to install in new construction as well as retrofit into existing parking structures. All high performance compact parking grilles are paired with our advanced Apex SmartController control panel, so programming and setting limits for your parking entrance gate is simple and will accept all activation systems. Safety is addressed with light curtains plus photo eyes to prevent potential harm or injury from the parking security grille. All compact parking grilles feature long lasting stainless steel links and a direct drive operator that eliminates sprockets and chains to wear or replace. You can customize perimeter parts and the grille manufactured to your exact specifications.When a low headroom security solution is required, Cornell’s MicroCoil high performance compact grilles are the only security grilles that are low on space, but high on performance.

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.
Static Wind LoadCan be manufactured to withstand a static wind load of up to 40 psf. If wind load is not specified,the MicroCoil Grille will be manufactured to withstand a 20 ultimate wind load.
Operational Wind LoadCan be manufactured to withstand an operational wind load of up to 20psf.
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.
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.
Sloping or Irregular OpeningsOur special bottom bar designs can address these conditions.
