Blank Spacer Patch Panel With Flanges

Our series of Blank Rack Spacers are a cut above the rest. Most people think of spacers or fillers as just that, something to fill up a gap in your rack to give it a fuller look. However, they serve a greater purpose than just aesthetics. They provide added strength so that each rack mounted component you install augments your racking system. Some racks can experience more than twice the strength and ruggedness by simply installing spacer blanks at regular intervals. We recommend installing either a component or spacer blank at least every 8U Spaces (17.5") for racks over 12U. Our Blank Rack Spacers with a Flange are available in 1U, 2U, 3U, and 4U to accommodate a large variety of applications, and include a durable black painted finish. They also feature rounded corners for optimum handling and installation safety.

Blanking Panel Accessories

Blanking panels offer a means to cover an unused rack space in front of a server rack. They promote circulation of airflow around the server equipment, while venting out hot exhaust from network components. By preventing the buildup of excess heat, cooling fans don't have to work as hard, which is energy efficient.
