The New 674 Security Grille: Security, Visibility, Air-Flow and Light in Stylish Aluminum

Commercial and retail property owners have an attractive new option 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. This makes the Model 674 an ideal solution for securing interior retail storefronts in retail facilities, airports, stadiums, malls and multi-purpose buildings because it 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™premium 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.
