Security Gates and 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, in front or behind a glass storefront or closed pharmacy counter.
Compact Grille Technical Sheet
Technical Detail Information
The SentryGate® combines high strength injection molded components with continuous metal rods. Its attractive brick pattern design is 65% open-air, for high visibility and ventilation. Our grille can be operated manually as a push-up or with a hand crank. If a motor is required, a standard motor, or compact integrated tube motor is available – key when headroom or aesthetics are of importance.
The SentryGate® provides:
- Ultimate security protection
- Easy retro-fitting to existing structures: The unit can bolt directly to existing wall constructions, frames or mullions, without the penalty of remodel downtime and cost
- Up to 5” less headroom than traditional rolling grilles for some designs
- Rugged curtain construction: SentryGate® curtains will maintain structural integrity and clean look, even with high cycle use
- Little or no routine maintenance

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.
Grille High Cycle ConstructionFor grilles that will cycle more than 5 times per day, such as parking garages and sally port openings, we recommend Model ESG12 brick pattern configuration. Alternative high cycle options include the Extreme SentryGate® grille and the Extreme 324 Grille.
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.
Motor Mounted Interlock
An overload sensing device that prevents damage if motor operation is attempted when the door or grille is locked. Field wired guide mounted interlocks are no longer necessary.
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.
Countertops are available for a complete counter shutter closure solution, and can be UL rated.Learn More
MullionsThere are multiple mullion options - corner, fixed and removable.
Sloping or Irregular OpeningsOur special bottom bar designs can address these conditions.
