How do I glue on the accessories?

PVC glue may be used to attached Mini Channel accessories to the drain itself.

Can I use rebar or any other method to stake the channel sections instead of the 6” channel installation stakes?

Yes. The recommended method install the channel is to drive a piece of ½” or 5/8” piece of rebar into the ground in the trench. Then drill small holes in the bottom flange of the channel. Next, insert tie wire into the hole and twist it onto the rebar such that the top of the channel sits 1/8” below the finished edge of the concrete. Example Below:
