High Security Extreme SentryGate Grille | Cornell Iron WorksSecurity Grilles
Model Number: ESG20 and ESG21
Commercial Security Grilles
Our most secure grille in the product line up, the SentryGate’s® patented design is an alternative to traditional rolling or counter grilles. Featuring a unique curtain comprised of injection molded components and continuous metal rods, the SentryGate® provides the ultimate protection to a parking garage entrance or in front of or behind a glass storefront or closed pharmacy counter.
The SentryGate’s patented design is an aesthetic alternative to traditional rolling or counter grilles and is available in white or black. The custom gate’s contoured curtain profile allows the unit to tightly store in an overhead coil. Also available in a compact model, the compact unit is installed in spaces where a rolling counter door would be used, such as pharmacy or concession counter openings. The full sized commercial security gate unit is typically used for full sized or very wide openings.
When you need a security grille that is heavy on security, light on weight, the SentryGate® has an efficient design that allows for interior mounting to existing construction.
Compact model (ESG 20) for openings 2’ wide by 1’6” high up to 14' wide by 10' high.Standard model (ESG 21) for all other openings up to 23' 4" wide by 14' high, or smaller doors which have high cycle requirements
If between jambs guide mounting is selected, minimum width is 2'11", minimum height is 2'7" high.
Maximum size for push up operation is 8' wide x 8' high.
Self supporting tubes only available with a face of wall mounting.
The doors are constructed for daily use and can withstand operation of up to 20 cycles per day – that’s 50,000 cycles for the lifetime of the door.
Standard Materials and Finishes
The SentryGate® combines high strength injection molded components with continuous metal rods spaced every two inches. The smooth finish is available in a black or white matte.
Surrounding components are clear anodized aluminum as standard. Optional finishes are black anodized or selected color powder coat finish.
Our doors can open by motor, hand-crank, or push-up operation, depending on size, weight and/or frequency of operation.

Smoother Installation and easy maintenance: 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. This ensures a secure seal without requiring you to overset the bottom door limit. The new sensing edge is easy to clean and remains free from rust and dirt stains, maintaining a fresh uniform appearance.
Edges are tested and listed to UL 10B as a component of the rolling steel fire door assembly.
Stronger weather protection: Featuring flexible 1" sealing fins, our sensing edges withstand the elements, providing maximum protection
Chain Diverter for MGH Operators
This option moves the auxiliary chain out of the clear opening and to the side of the door – enabling free movement through the door and making a chain bag unnecessary.
Grille curtain can be mounted in a fixed frame assembly. It can be installed separately, or installed near a rolling grille curtain to complement the aesthetics. Often used in parking garages.

Trim PackageIn applications where exterior aesthetics are important, such as hotels, condominiums, convention centers and parking garages, the addition of a trim package can cover unsightly hardware and contribute to the building's architecture.
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.
The Patent Pending Electronic AutoLock increases the overall security and strength of the Extreme High Performance Grille.

It's compatible with all operators that have a primary entrapment device and are configured for momentary contact to close. The Magic Switch is easy to retrofit in an existing application and features a clean, stainless steel face plate.
