The AP-series of blank rack panels for 19" wide EIA racks are made with 16-gauge aluminum and have a 0.625? flange for strength and rigidity. The panels mount flush to racks and are finished in a durable, scratch-resistant black wrinkle powder epoxy paint. They?re ideal for applications where the light weight and environmental attributes of aluminum are specified, and where the additional strength of a flanged panel is also necessary.
