Overhead Door Introduces Security Grille Model 674

Perforated Aluminum Panels Provide Security Plus Visibility, Air Flow and Light Infiltration

DALLAS – Commercial and industrial property owners have an attractive new option available for securing their interior spaces with the introduction of Overhead Door’s Model 674 Security Grille.

Engineered for inside applications, the Model 674 is a new perforated grille constructed from lightweight aluminum panels that provide security while maximizing visibility, air flow and light infiltration.

“The Model 674 is the answer for our distributors who need to provide their customers with an attractive security solution for interior spaces including retail facilities, airports, stadiums, malls and multi-purpose buildings,” said Jennifer Malcuit, rolling steel product manager at Overhead Door. “Like all our upward-coiling security grilles, this new Overhead Door system provides long-lasting high performance, but in a visually appealing package that won’t detract from its surroundings.”

Both inside and out, the Model 674 is designed to be aesthetically pleasing and functional. For example, its perforated aluminum curtain panels feature a clear, anodized finish or an optional PowderGuard™ powder coat paint finish to match interior surroundings. Meanwhile, the grille’s counterbalance assembly is composed of heavy duty, helical torsion-springs enclosed in a steel tube. The Model 674 even features continuous wear strips on guides to ensure ease of operation and noise reduction.

“With the Model 674, we’ve combined into one product the features our distributors and their commercial and industrial customers ask for most, including compatibility with an electric operation,” said Malcuit. “It truly is the ideal security solution for interior spaces.”
