Security 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.
