Video Doorbell Pro: Left/Right and Right/Left wedges

I'm interested in the Video Doorbell Pro but would need a left/right wedge.  One posting stated that SimpliSafe will send one of these wedges as needed.  It doesn't appear to be available for purchase. 

Questions:  What is the wedge's angle?  Is it adjustable?  What colors are available?  Can a picture be posted here?

Thanks.
