Clopay® Corporation, a leader in closure products for commercial, residential, industrial, institutional, and retail applications, introduces the Visionaire® MicroCoil® Grille, available through both the Cornell and Cookson brands, expanding its product line of security grilles featuring award-winning curtain technology. The patented, ultra-slim profile of Visionaire® MicroCoil® Grille requires nearly 30% less headroom than standard industry grilles. The curtain coils tightly and efficiently, providing a security solution for facilities with low headroom. Previously only available in high-performance construction, this technology is now available in standard-cycle, standard-speed rolling grilles. This product will be available in Clopay® Corporation’s Cornell and Cookson brands.
“By expanding the availability of MicroCoil® in a standard-cycle, standard-speed rolling grille, we are able to provide architects, designers and facility managers with a new range of security options for small spaces and retrofit projects,” said Siva Davuluri, Vice President of Marketing, Clopay® Corporation. “It is well suited for schools, urban retail applications, older buildings and structures that cannot utilize a standard size operating grille due to headroom and clearance restraints, or any structure that cannot be heavily altered,” he added.
A Plethora of New Applications
A major benefit of broadening the availability of MicroCoil® is its patented combination of technology, durability and aesthetics. The Visionaire® MicroCoil® Grille provides space-saving performance for facilities that do not require the speed and operation of high-performance rolling grilles.
“While our Extreme High Performance MicroCoil® Grille is a boon for busy parking facilities around the country, there are a number of retail and mixed-use applications that can benefit from low headroom coiling grilles that complement the building, while providing protection and security,” explained Heather Bender, Strategic Marketing Manager, Clopay® Corporation.
“In major cities around the country, historic buildings are often occupied by luxury retailers and high-end boutiques,” explained Jason Millard, Architectural Design Support - Project Manager, Clopay® Corporation. “Whether you’re in New York City, Boston, Philadelphia or Chicago, these spaces often have low headroom, and specifiers can’t change the physical structure and dimensions of the storefront. In order to provide security, they have traditionally relied on scissor gates, but now with Visionaire® MicroCoil® Grille, they have a compact, affordable option that is more robust, blends with the surrounding architecture and allows window shoppers to see merchandise after hours.”
Designed to Perform
Product engineers at Clopay® Corporation made several modifications to standard grilles in order to accommodate the curtain for the Visionaire® MicroCoil® Grille. The steel counter-balance coil shaft has been updated from a standard four-inch barrel to a more robust six-inch barrel. This allows the patented vertical chains to coil tightly and efficiently while providing a stiffer base to support the structure.
“The secret of Visionaire® MicroCoil® Grille is in the patented design of the curved links,” explained Millard. “The links increase in length as you move down the grille curtain. When the curtain retracts into the head unit, the increasingly longer links allow the grille to coil tightly and neatly stack into itself,” he added. The unique link construction also significantly reduces noise and vibration during motor or manual operations, making it one of the quietest grilles in the industry.
Visionaire® MicroCoil® Grille can be specified in a wide range of heights—from 6’ to 14’.5”—and widths up to 26’. The links are made of high-quality 304-gauge stainless steel and an easy-link repair system contributes to less maintenance, making repairs easy.
Visionaire® MicroCoil® Grille is rated and warranted to 50,000 cycles and comes with the brand’s full suite of safety and aesthetic features, including photo eyes, light curtains and powder coated finishes.
