A swivel mount assembly for rotational mounting of an electronic device includes an insertable part to be inserted into an opening in a structure and a lip part. A securing body secures the assembly body to a surface of the structure. A rotatable body includes another insertable part to be inserted into an opening in the insertable part of the assembly body, a plate part, side walls with at least one side aperture, at least one roller disposed in at least one opening in the plate part, a platform part disposed at an opposing end of the sidewalls to support the electronic device, and a hold/release mechanism disposed between the plate part and the platform part to hold the cable and prevent it movement when in a first setting and to release the cable and permit its movement when in a second setting.
