Figure 10. Key tabs at rear rail top and bottom edge
NOTE: As the key tabs and adaptors are pushed into the rear mounting holes, the spring clips will ride over the cabinet
channel and snap into place.
2. Holding the rail extended, push the key tabs and the adaptors into the rear mounting holes until the spring clips snap into
place on the outside of the rear cabinet channel.
Figure 11. Aligning the rear adaptors (left rear of cabinet shown)
3. At the front of the cabinet, making sure the rail is level, pull it forward and align the rail adaptor with the mounting hole in
the channel. Push in on the spring clip while pulling forward on the rail. When the spring clip is forward of the front cabinet
channel, and the adaptor is in the mounting holes, release the spring clip so it holds the rail in place.
CAUTION: Ensure the spring clip is securely attached to the channel. It may be necessary to push in on the
clip to assist in snapping it into place.
