SentryGate® GrilleSecurity Grilles
Model Number: ESG20 and ESG21
Smooth Finish Roll Down Gate
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.

MullionsThere are multiple mullion options - corner, fixed and removable.
Sloping or Irregular OpeningsOur 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 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.
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.
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.Learn More
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.Learn More
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.
LED Visual Light KitThe LED Light Kit provides a high-visible status indication for overhead doors and grilles. Designed for challenging environments like fire and emergency services, parking garages, and warehouses, the effective LED light strips limit downtime, maintenance, and repair costs.
Magic SwitchA touchless activation device designed to open and close doors with the wave of a hand. 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.
