In need of a standard cycle, low head room grille for retail applications? The Visionaire® MicroCoil® Grille is the ideal solution. With nearly 40% less headroom than any other standard grille on the market today, the Visionaire MicroCoil offers unmatched benefits and aesthetics. Engineered to be compact, quiet and reliable, its unique features make it ideal for a wide range of applications such as retail, city storefronts or historic buildings that cannot be heavily altered.

The grille curtain matches the design of our unique High Performance MicroCoil Grille featuring 304 stainless steel links. The sleek links nest on top of one another when the grille coils closed requiring as little as 15.5” of headroom. The links are easily replaced, allowing this grille to boast a lifetime of less maintenance and simple repairs. Speaking of the curtain, it offers a flexible design in either a straight or brick pattern.

Engineered for longevity, the Visionaire MicroCoil has a lifespan of up to 50,000 cycles. Whether you are looking for a motor or a manual operation such as chain hoist or push up, the Visionaire MicroCoil can meet your needs.

When you need a low headroom, low cycle grille with unparalleled aesthetics, Cornell’s Visoinaire MicroCoil is the ideal solution.
