Product update:

Since posting this video we have changed suppliers and are using different mollies. Please pre-drill with 1/4" bit (new models - after 1-1-2018) and not 5/16" (older models) Even so it says in the video below to pre-drill with 5/16"

Three bike installation:

 Please use 1/4" drill bit for mollies.

(not a 5/16" bit that I mention in the video below)
