The Juniper Networks SA-805 Frame Mount Bracket Kit is compatible with the BTI800 Series Ethernet Access packet optical networking system. The single and dual mount rack kit is packaged in one box. The single rack mount kit consists of right and left L brackets, and the dual rack mount kit consists of 4 L brackets and 3 connector plates. The L brackets are installed in different orientations to allow the SA-805 to be mounted onto a 19-inch, 21-inch, or 23-inch rack. The mounting brackets and connecting plates all use the same screw type: M3 x 6 flat head Phillips screws, which are included in the kit.
