Security Grilles
Model Number: ESG20 and ESG21


For a smooth finish and sleek look compared to other security gates, our SentryGate offers an alternative patented design comprised of high strength injection molded components with continuous metal rods. Available in white or black 65% open brick pattern, the long lasting contoured profile allows the rollup gate to store tightly overhead while still providing high visibility and ventilation. Our compact version features a compact integrated tube motor, taking up to 5” less headroom than traditional overhead coiling grilles. The compact rolling grille version is perfect for security solutions where a counter door would be used, such as concession stands or pharmacy counters without losing visibility. 

The SentryGate roll down gate is easily to retrofit into existing structures as it can bolt directly to existing construction and frames saving remodeling downtimes and costs. The compact rolling gate model provides installation opportunities in small overhead spaces.

For a smooth clean look that is heavy on security but light on weight, the SentryGate is the security gate solution you have been looking for.

Compact model (ESG 20) for openings 2’ wide by 1’6” high up to 14′ wide by 10′ high.


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.

Available Operators
Our doors can open by motor, hand-crank, or push-up operation, depending on size, weight and/or frequency of operation. 

Model MG – A medium duty operator for doors that will cycle no more than 20 times per day

Model SG – A super duty, full logic operator for larger doors or doors which may periodically cycle more than 20 times per day (used with Extreme® option).

Tube Motor – If aesthetics or strict dimensional limitations around the header are key, our concealed tube motor is a much smaller operator – and available only with the compact model

Countertops are available for a complete counter shutter closure solution, and can be UL rated.

There are multiple mullion options –  corner, fixed and removable.

Sloping or Irregular Openings
Our special bottom bar designs can address these conditions.

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.Learn More

Manual Release System
If egress is required on a motorized grille, a wall mounted pull handle disengages the motor to allow the grill to partially open.

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.

Fixed Panels
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.

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.

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.

Trim Package
In 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.
